Heat relaxation phenomena at low temperature in amorphous LaZn

Abstract

An anomalous heat relaxation with a very long time constant (about 60 h) has been observed in amorphous La0.78Zn0.22. The total heat release is about 1.5 mJ per gram of sample. This phenomenon can be attributed to the ortho-para transformation of hydrogen trapped in the sample. This behavior disappears after crystallization.
