Abstract

The effects of phosphorus on the magnetization of nickel have been examined for thin films made by electroless deposition, electrodeposition, and by vacuum evaporation. While P has a very low solubility in bulk nickel, the results indicate that all three processes result in a metastable solid solution of P in Ni, which is transformed into the stable (paramagnetic Ni3P plus Ni) configuration by annealing at 850°K. The concentrations of P in the deposited films were varied and quantitatively established through the use of NaH232PO2 in the deposition process, coupled with radio-analysis techniques. The magnetic data obtained are in qualitative agreement with z=5 in the expression, μB=n0-cz, where n0 is the number of holes in the 3d band of nickel, c is the concentration of phosphorus, and z its valence. Data on the behavior of magnetic moment and Curie temperature with P content are presented and a tentative explanation put forth for some anomalous behavior of these parameters. © 1967 The American Institute of Physics.
