Nonlinearities in composition dependence of structure parameters and magnetic properties of nanocrystalline fcc/bcc-mixed Co-Ni-Fe thin films

Abstract

In this report, the nonlinearities are analyzed in fcc-to-bcc (fcc/bcc) population ratio, lattice parameters (aexpfcc aidealfcc and aexpbcc aidealbcc) and saturation magnetization (ISobs ISa) of the electrodeposited thin Co-Fe-Ni films as a function of average number of electrons in the alloy (ne), which proved to be a convenient way to follow the variation of chemical composition. The enhancement of the saturation magnetization correlated with the nonlinear deformation and connected with a complicated rearrangement of the outer shell electron configurations due to change in composition in a disordered alloy. © 2008 American Institute of Physics.
