Closing the Performance Gap: Development of High-Precision Magnetic Encoder Systems using Advanced TMR Sensing Technology and Magnetic Pole Patterns written on Sputtered SmCo-Layers
by Florian Slanovc of Silicon Austria Labs (SAL)

Despite their cost-effectiveness and robustness, magnetic encoder systems have historically trailed optical encoders in terms of ultra-precise measurements. To address this performance disparity, our research collaboration is pushing the boundaries of magnetic encoder technology by integrating high-performance TMR sensing, a few tens of micrometres thick sputtered SmCo-layers, and advanced magnetization techniques. This presentation will discuss the design, simulation, and characterization methodologies employed to optimize these systems, including SmCo-layer structural and phase analysis via X-Ray Diffraction (XRD), magnetic hysteresis property evaluation using a Vibrating Sample Magnetometer (VSM), simulated batch testing of magnetization processes, high-precision pole wheel scanning, and magnetic pattern visualization using a magnetic field camera. By leveraging these cutting-edge technologies and techniques, our research aims to significantly enhance the precision and accuracy of magnetic encoder systems, enabling new applications and use cases that demand ultra-high performance.

Use of HRE-free magnets: calculation of demagnetisation resistance and its behaviour over time - Application to actuator operating at high temperatures
by Javier Rios Quesada of Moving Magnet Technologies SA

MMT has developed a bistable permanent magnet actuator with double reciprocal output pins used to drive a combustion engine camshaft. This actuator is subject to strong thermal stresses (operating temperature up to 155 °C) which led the manufacturer to use magnets strongly dopped with Dysprosium (40AH). The current rare earth export Chinese policy pushes the actuator manufacturers to evaluate alternative solutions to avoid shortage. With the constraint that the specifications could not be changed. One of the alternatives is the replacement of the origine magnets by new magnets without rare earth (HRE free), but with lower intrinsic coercivity and so, sensitive to demagnetization. A demagnetization study workflow has been set up to calculate the working point at each single element of the actuator magnets, exposed to the most demanding conditions. A magneto dynamic simulation considering the characteristic of the magnet and especially their demagnetization behaviour was made to determine the performance losses of the actuator and to ensure that once the actuator has been subjected to the worst case of demagnetization there is no further evolution of the performances. Measurements with the new magnets were conducted and our simulations workflow validated. For this talk we propose a quick presentation of the actuator technology, the study of the workflow set up in the framework of magnetostatic 3D simulations (but transposable to 2D simulations) and the presentation of dynamic simulations as well as measurement results.

Injection Molded Magnets for Electrical Machines
by Thomas Schliesch of Max Baermann GmbH

Injection molded magnets are applied for electrical machines in high quantities especially when less power, but complex field distributions or geometrical shapes are needed. The magnets are either in-mold oriented cost-effective Ferrites which are magnetized directly inside the mold or rare earth magnets, which are additionally magnetized by external pulse magnetizing. For an adequate prediction of the magnets’ behavior specific analysis tools are needed. After an overview over injection molded magnets including materials, tooling and mechanical system aspects, the analysis methods will be explained by practical examples, where predictions from calculations will be compared to measurements. A special focus will be directed towards the comparison between NdFeB and SmFeN specimen.

High Entropy Intermetallic Compounds: A novel approach to widen the lanscape of intermetallic compounds suitable for permanent magnet applications
by Dimitrios Niarchos of AMEN NEW TECHNOLOGIES

The European Green Deal and the accelerating energy transition place unprecedented demands on advanced functional materials for electrification, renewable energy, hydrogen technologies, and sustainable chemical processing. While intermetallic compounds are central to these technologies—most notably in permanent magnets and catalysis—their development is heavily bottlenecked by narrow compositional flexibility, phase instability, and a critical dependence on geopolitically sensitive raw materials. Overcoming these limitations requires a new materials design paradigm that simultaneously maximizes performance, sustainability, and supply-chain resilience.

Wafer-level rare-earth micromagnets: enabling a new generation of miniaturized devices
by Milan Calic of MagnetFab

The miniaturization of devices relying on permanent magnets is increasingly constrained by the limitations of conventional permanent magnet manufacturing technologies, which become impractical at sub-millimeter dimensions. We present a wafer-level technology for fabricating high-performance rare-earth micromagnets directly on semiconductor wafers using physical vapor deposition in combination with established semiconductor microfabrication techniques, making permanent magnets compatible with semiconductor manufacturing. This presentation will discuss the technological challenges associated with conventional permanent magnet miniaturization, introduce the key features of the wafer-level micromagnet technology, including its magnetic performance, scalability, and compatibility with semiconductor manufacturing, and illustrate its potential through examples including a miniaturized MEMS loudspeaker and trapped-ion quantum computers.

by Sorana Luca and Emilie Sueur of CEA-Liten and Orano

This presentation introduces the high-performance NdFeB permanent magnet pilot production line developed by CEA and Orano in Grenoble, France. With an annual production capacity of 4 tons, the facility aims to manufacture state-of-the-art sintered magnets for strategic applications, including electric mobility and offshore wind energy. Particular attention will be given to approaches aimed at reducing the use of Critical Raw Materials, especially through the implementation of short-loop recycling of end-of-life (EoL) NdFeB magnets, contributing to a more resilient and sustainable rare-earth value chain.
