Orbital ferromagnetism and anomalous Hall effect in antiferromagnets on distorted fcc lattice

arXiv:cond-mat/0108322 · doi:10.1103/PhysRevLett.87.116801

Abstract

The Berry phase due to the spin wavefunction gives rise to the orbital ferromagnetism and anomalous Hall effect in the non-coplanar antiferromagnetic ordered state on face centered cubic (fcc) lattice once the crystal is distorted perpendicular to (1,1,1) or (1,1,0)- plane. The relevance to the real systems -FeMn and NiS is also discussed.
