A Tunnel Diode Oscillator for High Sensitivity Broad Temperature Range Susceptibility Measurements
arXiv:2109.11030
Abstract
We report the design and operation of a versatile tunnel diode oscillator for high sensitivity (50 ppb) measurements of the magnetic susceptibility of samples over a wide temperature range (1.7-100 K) that can be used with a simple liquid helium storage dewar. The design allows for the application of an electric field across the sample to search for magnetoelectric effects.
