Large Orbital Magnetic Moment in Febr2
arXiv:cond-mat/0008274
Abstract
Magnetic moment of the Fe2+ ion in FeBr2 has been calculated to be 4.32 mB in the magnetically-ordered state at 0 K. It is composed from the spin moment of 3.52 mB and the orbital moment of +0.80 mB. These calculations show that for the meaningful analysis of e-m properties of FeBr2 the spin-orbit coupling is essentially important and that the orbital moment is largely unquenched.
