摘要：

A system of classical spins defined on a simple cubic lattice. and interacting via a competing antiferromagnetic superexchange and ferromagnetic double-exchange nearest-neighbor coupling, has been studied with Monte Carlo simulations, The phase diagram of the model includes two regions with nearest-neighbor spin canting.
