Abstract
A spinel-type oxide exhibiting a cooperative Jahn-Teller effect shows an extraordinary reduction of sound velocity therethrough at temperatures near the Jahn-Teller phase transition temperature thereof. The sound velocity and effective temperature range can be varied over wide ranges by using a solid solution of such an oxide and another spinel-type oxide not exhibiting the Jahn-Teller effect. NiCr.sub.2 O.sub.4 and ZnCr.sub.2 O.sub.4 are particularly advantageous as the former and latter oxides, respectively.
