The Magnetic Properties of Certain Pt-Co and Pd-Co Alloys

Nanostructure characterization of Co–Pd–Si–O soft magnetic nanogranular film using small-angle X-ray and neutronscattering

“…There is a lot of magnetic data available for bulk Co-Pd, as well as the crystal structure, because Co-Pd is a well-known magnetic material in which Co induces a magnetic moment in Pd. Many studies about magnetic properties of Co-Pd have been carried out [37][38][39]. Since Si-O is also a popular material, there is similarly a large amount of data [40,41].…”

Contribution of the spin current to the damping of the magnetic moment precession of Fe impurities in Pd

“…Experimental results indicate that the susceptibility of Pd has a Stoner enhancement factor of about 10, and one can consider Pd as nearly ferromagnetic. The experimental works with dilluted impurities of Mn, Fe and Co on Pd revealed magnetic moments of, 8µ B , 12.6µ B , and 10.8µ B , respectively, which corresponds extended cloud with a large number of polarized atoms [1].…”

“…The behavior of the Pd-based diluted alloys has attracted much attention since the first experiments indicated the appereance of a giant magnetic moment surrounding the magnetic impurities' sites, [1]. This effect is understood as a consequence of the strong polarization of the host atoms by the impurity, creating a polarization cloud.…”

Giant magnetic moment dynamics in Pd

“…The Coulomb interaction parameter is Fe 1 U = eV at the Fe site [10], Pd 0 4 U = . eV at the surrounding Pd atoms and 0 U = everywhere else in the system 1 . The ferromagnetic ground state is obtained self-consistently in mean-field approximation, by imposing local charge neutrality on each of the magnetic atoms.…”

“…Since the work of Constant [1] on Pd based diluted alloys, many experiments have indicated the appearance of large magnetic moments per atom, referred to as giant magnetic moments. This effect can be understood in terms of a strong polarization of the host by the magnetic impurity, producing a large polarization cloud.…”
