The temperature dependence of elastic constants of quenched Fe. .Al. (.X'=0.26,0.30 and 0.32) single crystals was measured by a ultrasonic pulse-echo technique from4.2 K to 300 K under applied magnetic fields. For the ferromagnetic alloy withx=O.26, the IE effect was observed in the C3. mode. The reentrant spin glass alloywith ,X'=0.30 also shows the AE effect in C.. above 90 K, which corresponds to thereentrant spin glass freezing temperature, T,. Below T. the AE effect completely disap-pears, indicating freezing of spins or magnetic clusters. In the spin glass alloy withx=O.32 a slight softening of C.. was observed around T. determined by magnetiza-tion measurements. These observations indicate that the elastic measurement pro-vides an useful experimental method of determining the spin glass freezingtemperature, in particular, for reentrant type spin glasses.
