New system for high sensitivity study of magnetoelectric effects

ORAL

Abstract

We report a novel experimental technique for studying magnetoelectric couplings in matter using a tunnel diode to power a specially designed coil cell. The system can detect small changes in frequency of 0.5 ppm, allowing precise measurement of magnetic susceptibility induced by an applied electric field. This system operates over a temperature range from 1.8 K to 100 K, while maintaining the tunnel diode at superfluid helium temperature. The aim of this device is to study magnetoelectric couplings in molecular magnets and spin crossover systems.
