By films of iron, nickel, and cobalt are here meant electrolytic deposits of these metals on platinised glass. The magnetic properties of such films are interesting in various ways. For example, when they are longitudinally magnetised, we have the case of a magnet where the ratio of length to breadth is very great, and where, consequently, the demagnetising force is very small, e.g., with a film of a 5000th part of a millimetre in thickness, and 5 mms. in length, we have a ratio in length to thickness of 25,000: 1; at the same time the film is so small that it can be tested in very high uniform fields.

The self-diffusion of nickel and the diffusion of Ni63 into iron, cobalt, and two iron–nickel alloys was studied using the technique of decrease in surface activity, The nickel self-diffusion results are compared to previously reported values. Nickel is found to diffuse more slowly than iron in the iron-rich portion of the iron–nickel system. The rate of nickel diffusion increases with increasing nickel content. A comparison is made between the present results for diffusion of Ni63 into iron, cobalt, and nickel with reported values for diffusion of Co60 and Fe59 in the same metals. In each solvent, the magnitudes of the activation energies, Q, are such that QNi > QCo > QFe.

ABSTRACTSonoelectrochemistry, or pulsed electrodeposition at high current density in presence of high intensity ultrasound, is used to produce magnetic powders with a mean diameter in the range of 100 nm. Pure iron, cobalt and nickel powders are produced together with their binary and ternary alloys. The powders are crystalline and homogeneous as observed by scanning and transmission electron microscopy, electron diffraction and X-ray fluorescence. The compositions of the binary and ternary alloy powders reproduce strictly the iron, nickel and cobalt compositions of the starting electrolytes except for the nickel-cobalt alloys.
