Optics of a ferromagnetic superlattice with noncollinear orientation of equilibrium magnetization vectors in layers

The transmission and reflection of a normally incident wave from a magnetic superlattice consisting of 2N ferromagnetic layers with alternating orientation of the magnetization vector in the layers, separated by nonmagnetic interlayers are considered. The characteristic matrix of the superlattice and Jones matrices determining all the basic magnetooptical characteristics of the structure (transmission and reflection coefficients, the degree of polarization of transmitted and reflected waves, and so on) are calculated in closed form. A significant dependence of these characteristics on the number of layers and thickness of interlayers is demonstrated.
