Microscopic theory of magnetoresistance in ferromagnetic materials
The magnetoresistance (MR) effect, which stems from the spin-exchange coupling between local moments and itinerant electrons in magnetic materials, is a challenging many-body and open-quantum problem. Here, we develop a comprehensive microscopic theory of MR from an open-quantum system perspective. The theory not only predicts the magnetic field and temperature …
