本文提出了超导体磁光特性中二向色性的微观理论。四个不同的机制，在超导体的二向色性被确定。两个是从正常状态已知的机制的修改，两个是在超导体中发现的新效应。通过对一个简单模型系统的数值计算，说明了该理论。相对论对称性破缺和超导相干性之间的相互作用被发现产生了各种新的效应，不知道从正常状态下的二向色性。{版权} {美国物理学会}
A microscopic theory of dichroism in the magneto-optical properties of superconductors is presented. Four distinct mechanisms for dichroism in superconductors are identified. Two are modifications of mechanisms known from the normal state, and two are novel effects found in superconductors only. The theory is illustrated by numerical calculations for a simple model system. The interplay between relativistic symmetry breaking and superconducting coherence is found to give rise to a variety of new effects, not known from dichroism in the normal state. {copyright} {ital 1997} {ital The American Physical Society}
