New class of materials for optical isolators
Applied Optics Vol. 22, Issue 20, pp. 3152-3154 (1983) •doi: 10.1364/AO.22.003152

Experimental measurements are presented to demonstrate the isolator capabilities of a new class of magnetooptic materials called dilute magnetic semiconductors. The specific sample used is Cd0.55Mn0.45Te, and it is shown to exhibit significantly better performance than other magnetooptic materials available for use at wavelengths shorter than 1.0 μm.
