Pulsed field magnetometer for low-temperature study of high-performance permanent magnets

A pulsed magnetometer is useful for testing high-performance magnets because it can produce high magnetic fields that are sufficient to magnetically saturate them. We installed a cryostat in a pulsed magnetometer and tested several prevailing permanent magnets at low temperatures. The measurements were successfully performed down to 4.2 K, and it was shown that a pulsed magnetometer is useful for low-temperature measurement on permanent magnets as well as room-temperature measurements.
