Abstract
Measurements are reported of the longitudinal and transverse elastic moduli of the R2Fe14B compounds having rare-earth component R=Ce, Pr, Nd, and Er. A resonant ultrasound technique was used to determine the elastic constants on hot-pressed, melt-spun samples which are essentially isotropic, polycrystalline specimens of the four compounds. The results for Nd2Fe14B, which agree well with previous studies, and Er2Fe14B exhibit clear signatures of the spin reorientations which occur in those compounds. No such signature appears in the data for Pr2Fe14B, consistent with the fact that no spin reorientation occurs in that material. The ultrasonic attenuation of each sample has also been measured and it has been found that it shows features in the vicinity of spin reorientations (Nd2Fe14B, Er2Fe14B) and the Curie point (Ce2Fe14B).
