Magnetic anisotropy properties of Co compounds — •Ingo Opahle1, Lutz Steinbeck2, Manuel Richter1, Michael Kuzmin3, Klaus Koepernik1, and Helmut Eschrig11IFW Dresden, P.O.B. 270016, D-01171 Dresden, Germany — 2ZMD Dresden, Germany — 3Instituto de Ciencia de Materiales de Aragon, Zaragoza, Spain

Magneto crystalline anisotropy properties of rare earth transition metal compounds have been calculated using the highly accurate relativistic FPLO method and the relativistic optimized LCAO method. The effect of the lattice geometry and orbital polarization, a correction to the LSDA taking into account Hund’s second rule, are discussed. Results are presented for RCo5 and R2T17Nx compounds and compared to experimental data.
