Abstract

In order to investigate the alloying effect in Ni/Pd nanoparticles, a special chemical reaction method has been developed to generate a sufficient number of well-conformed Pd ultra-fine particles. Ni concentration dependence on magnetization reveals the existence of a giant magnetic moment effect, where the critical concentration of 6.3 at% is higher than the bulk state one. The higher harmonics intensity of ESR is remarkably enlarged in the alloying particles. The enhanced spectra with ΔS = 2 and the broad spectra arise from the nonlinear effect of the isolated nanoparticles with a long spin-lattice relaxation time.
