Recent research work has concentrated on the magneto-optic properties of macroscopic ferrimagnets. For example, a new class of two phased materials, called macroscopic ferrimagnets, displays many properties associated with ferrimagnetism including magnetic compensation points. A typical material system which shows this pheomenon is cobalt containing approxiamately 100 Angstrom precipitates of EuS. The negative exchange in these systems is relatively weak so the remanent magneto-optic properties show the ferrimagnetic state, but at fields above 2 to 3 T, alignment of both the Co and EuS with the field can occur. In addition to the usual magnetic compensation point at which the sign of the magneto-optic loop reverses, we observe a second, magneto-optic, compensation point which occurs when the Kerr rotation of the two phases are equal and opposite. Another recent research work involves the magnetoresistance of thhe Co-EuS macroscopic ferrimagnets. The magnetoresistance of Co-EuS is negative at room temperature but becomes positive at 4.2K. This MR temperature dependence is attributed to interface scattering at the boundary of Co metal with EuS particles when the two magnetic phases are antiferromagnetically exchanged coupled and have a compensation point at low temperatures.
