Electric Field-Induced Modification of Magnetism in Thin ...

Jan 19, 2007 · A large electric field at the surface of a ferromagnetic metal is expected to appreciably change its electron density. In particular, the metal's intrinsic magnetic properties, which are commonly regarded as fixed material constants, will be affected. This requires, however, that the surface has a strong influence on the material's properties, as is the case with ultrathin films.

The temperature dependence of magnetic susceptibility was studied on the anhydrous and hydrous modifications of the potassium-chloranil salt. While the anhydrous salt exhibits a phase transition at 210-270 K from the low spin state to the high spin state, the hydrous modification shows no such phase transition, and remains in a low spin state over the whole temperature range, 70-300 K.
