Vv. Filippov, INFLUENCE OF A THIN DIELECTRIC LAYER ON NONRECIPROCAL EFFECTS ARISINGAT THE REFLECTION FROM MAGNETOOPTIC FILMS, Journal of magnetism and magnetic materials, 148(1-2), 1995, pp. 289-290
An additional transparent dielectric layer allows to create an antires
onant light-wave field distribution in layered structure, containing a
bsorbing magneto-optic (MO) film. This results in nonreciprocal phase
shift enhancement with simultaneous decrease of nonreciprocal losses a
nd low level of total losses.
