摘要：

The relationship between the classic Curie-Weiss law and the Barrett formula is discussed. In order to remedy obvious discrepancies a generalization of the Barrett formula is proposed. Introducing a new quantum temperature scale, the long-standing Barrett expression may be transformed into a Curie-Weiss-like quantum power-law. (C) 1998 Elsevier Science Ltd. All rights reserved.
