摘要：

Elastic constants of Nd2Fe14B and Y2Fe14B have been measured from 4.2 K up to above the Curie temperature by means of an ultrasonic pulse echo method. The ordinary ΔE effect has been observed only in the shear modulus of Nd2Fe14B below 150 K. A softening in the longitudinal modulus was observed for both compounds below TC, which is explained as an inverse effect of the volume magnetostriction. © 1989.
