Research and Development of Rare Earth-Transition Metal Alloys as Permanent-Magnet Materials.
Abstract
The results of room temperature saturation magnetization and anistropy measurements made using an oscillating specimen magnetometer are reported for single crystals of the compositions Pr2(Co(1-x)Fe(x))17, x = 0.2, 0.3, 0.4 and Y2(Co(1-x)Fe(x))17, x = 0.1, 0.2, 0.3. Measured values support earlier measurements made on packed powders of the same compositions. Values for the anisotropy constants, K1 and K2, are also given. The cerium-cobalt alloy system has been re-examined and a revised phase diagram is proposed. The thermal stability of the RCo5 phase was investigated in CeCo5, PrCo5, and NdCo5 using metallography, scanning electron microscopy, electron probe microanalysis, differential thermal analysis and thermomagnetic analysis.
