摘要：
The temperature behaviour of spontaneous magnetization and spin heat capacity of amorphous ferromagnets near the absolute zero is shown to follow the Bloch law. With rising temperature, however, the magnetization decreases and the heat capacity increases much more rapidly than in the crystal state. This is attributed to the decrease of magnon hardness and to the interaction of magnons with density fluctuations.
