An electrostatic driven vibrating sample magnetometer especially suitable for magnetic anisotropy measurements

A simple vibrating sample magnetometer, operating from 4.2 to 300 K, has been developed. The sample is forced to vibrate vertically with a fixed frequency and amplitude, as is usual for this type of magnetometer. The vibration is obtained through an electrostatic excitation of a resonance mode in a high Q mechanical vibration unit. Supplied with 'perpendicular' detector coils, the instrument is very suitable for accurate determinations of both high and low magnetic anisotropy.
