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.

The electrochemistry of a number of aminoquinones and quinone thioethers has been investigated in aqueous-ethanol solutions. Half-wave potentials as a function of pH have been measured polarographically and heterogeneous rate constants for several of the compounds have been determined by cyclic voltammetry. The E1/2's and the ks.h'S have been compared with hyperfine splitting constants determined by ESR spectrometry and conclusions arrived at as to the effect of spin density on electrochemical parameters.
