Novel system for measuring magnetic susceptibilities over a wide temperature range

ORAL

Abstract

We discuss the design and operation of a new type of tunnel diode oscillator for measuring magnetic susceptibilities with high sensitivity over a wide temperature range. The tunnel diode is maintained at a fixed low temperature for maximum sensitivity while the sample can be varied from 1.7 K to 100 K. This design provides an optimized system for searching for unknown magnetoelectric couplings in molecular magnets and spin crossover systems.
