Thin films of a ternary Ni‐Fe‐P alloy suitable for use in computer memories have been electrodeposited from a sulfate bath containing sodium hypophosphite. Glass coated with conductive vacuum evaporated layers of chromium and gold was used as a substrate. Essentially nonmagnetostrictive films, 1200Aå thick and 3×3 in. in area, with coercivities of 2 oe and anisotropy fields of 3.5 oe were prepared reproducibly. The effects of hypophosphite ion in the plating solution on the deposit composition, cathode potentials, and magnetic properties of the films are discussed.

The infrared spectra of gaseous ClCN and BrCN at room temperature are reported for the LiF, NaCl, KBr, and CsBr prism regions. Several upper stage bands as well as bands due to C13 appear in both spectra. Assignments are given, from which a number of the vibrational constants are evaluated and the Fermi resonant levels treated by a first-order perturbation method. The spectra of crystalline ClCN, BrCN, and ICN at −180°C is also recorded. Absorption bands, including several due to C13 and N15, are assigned and the spectra are discussed in terms of the available x-ray crystal data.

Thin magnetic films of nickel‐iron‐molybdenum, 600–800Aå thick, were electrodeposited from citrate complexed solutions containing sodium molybdate, nickel sulfate, and iron sulfate. The variation of magnetic properties of the films was determined as a function of the composition of the film, the pH of the plating solution, and the current density. All experiments were carried out at room temperature. Glass slides with vacuum evaporated chromium‐gold layers were used as substrates. Magnetic films with Hk values of 1.0 oe have been obtained from these solutions.
