Pulse measurements of the magnetoelectric effect in chromium oxide

Apparatus is described in which the magnetoelectric susceptibility along the axis of a disk-shaped sample of material may be measured. In one apparatus a pulsed magnetic field is applied, and the resulting eleciric polarization is measured, while in another apparatus an electric field, which increases linearly with time, is applied to the disk and the resulting magnetization is measured. The pulsed magnetic field apparatus proved to be the best system for making measurements and a bandwidth of several megacycles per second was achieved.
