Notes:
Pd and Pt have been shown to be highly polarizable when mixed with ferromagnets like Ni, Fe, and Co. In these alloys the total moment, or magnetization cloud, is produced by the magnetic moment plus the induced moment on the surrounding atoms. With diffuse magnetic scattering of neutrons, it is possible to measure these magnetization clouds, M(K), as Fourier transform of the moments; M(K) represents the site occupation magnetic moment correlation. We consider that the atoms of the matrix polarize around the atoms of the impurity, following the orientation of its moments and forming giant moments. To compare with experimental data, we obtained an expression for the magnetic moments assuming a local magnetic environment. We then developed an expression for the magnetization cloud that includes the total moment associated with a giant moment, M(0), determined by magnetization measurements; we used M(0)=dμ/dc, where μ is the average moment of the alloy and c the impurity concentration, to establish a relation between neutron and magnetization measurements. © 1997 American Institute of Physics.
