Magnetostatics of synthetic ferrimagnet elements
arXiv:1006.5531 · doi:10.1016/j.jmmm.2011.07.020
Abstract
We calculate the magnetostatic energy of synthetic ferrimagnet (SyF) elements, consisting of two thin ferromagnetic layers coupled antiferromagnetically through RKKY coupling. We calculate exact formulas as well as approximate yet accurate ones, which can be used to easily derive energy barriers and anisotropy fields of SyF. These can be used to evaluate coercivity, thermal stability and other useful quantities.
