Abstract
For light traveling perpendicular to the magnetization in a ``cubic'' magnetic crystal, the normal modes are linearly polarized parallel and perpendicular to M. The difference in the velocities of these modes constitutes a Linear Magnetic Birefringence (LMB) which may be easily observed. Measurements of retardation for M∥ [100] and for M∥ [111] are needed to specify the LMB for a cubic crystal. These quantities R100 and R111 have been measured at 77° and 300°K for each of the rare‐earth iron garnets. With the notable exception of TbIG and SmIG, there is evident a correlation between the LMB and the magnetostriction.This publication has 1 reference indexed in Scilit:
