On T-violation signals originating from magnetic orders through double exchange mechanism
arXiv:cond-mat/9805303
Abstract
The photon self energy tensor in a crystal with double exchange and ferromagnetic or canting magnetic orders is analyzed at zero temperature with emphasis on the signal of the time-reversal invariance breaking. Three comparable contributions, spin susceptibility, local magnetic field and spin-orbit coupling are estimated and the prospect of their experimental detection is discussed.
