Elastic constants of NdlFe,,B and Y:Fe,,B have been meawred from 4.2 K up to above the ('uric tcmperaturc b! means of an ultrasonic pulse echo method. The ordinary ?rE effect has hcen observed only In the shear modulus 01 Nd,Fe,,B below 1X1 K. A softening in the longitudinal modulus was observed for
