There are evidences of pressure-induced high-spin to low-spin transition in pyrite type MnS2 and MnTe2. Are there any other compounds which undergo such transition?
It is well-known that the symmetry of the nonlinear optical susceptibility is strongly affected by a magnetization or an external applied magnetic field. Thus it is of considerable interest to...
