Abstract:We present an experimental and computational investigation the Neodymium thickness dependence of the effective damping constant (α_eff) in Ni80Fe20/Neodymium (Py/Nd) bilayers. The computational results show that the magnetic damping is strongly dependent on the thickness of Nd, which is in agreement with experimental data. Self consistent solutions of the spin accumulation model and the local magnetisation were used in the simulations. It was not possible to obtain agreement with experiment under the assumptio… Show more
