Repm Exhibit to Highlight Use of Lake Shore Magnetometers for Permanent Magnet Research

Share Article

Lake Shore will showcase its vibrating sample magnetometers at the rare earth and permanent magnets exhibition.

Lake Shore 3900 MicroMag VSM

Lake Shore MicroMag™ VSMs can be used to perform first-order-reversal-curve (FORC) measurements, which provide information on important magnetic interactions in permanent magnetic materials.

Lake Shore Cryotronics, a leading innovator in solutions for measurement over a wide range of temperature and magnetic field conditions, announced today that it will be discussing magnetometer systems for characterization of magnetic materials during next week’s Rare Earth and Future Permanent Magnets (REPM) workshop in Annapolis, Md.

During the Aug. 17–21 workshop, Lake Shore will specifically highlight its PMC MicroMag™ 3900 Series vibrating sample magnetometers (VSMs) and 7400 Series VSMs for their use in measuring the magnetic properties of permanent magnet materials. The company will also highlight the utility of first-order-reversal-curve (FORC) analysis, which provides information regarding irreversible magnetic interactions in permanent magnet materials, information that cannot be obtained from a standard hysteresis loop measurement alone.

The PMC MicroMag™ 3900 VSM provides for measurements to 2.2 T over a temperature range from 10 K to 800 °C, and the 7400 VSM provides for measurements to 3.1 T over a temperature range from 4.2 K to 1000 °C.

In addition to magnetometer systems, the Lake Shore magnetic measurement and control product line includes electromagnets, electromagnet power supplies, gaussmeters, fluxmeters, Hall probes, and Helmholtz and search coils for direct testing of permanent magnetic components.
