Popis:	The method of Bates and Weston for measuring the small heat changes which occur as a ferromagnetic substance is taken through a single hysteresis cycle step by step has been extended to some seven ferromagnetic alloys. In every case a cooling is initially observed as the magnetization of the specimen is reduced from its maximum value. Indications are found that large changes in thermomagnetic properties are caused by small changes in composition, particularly when the latter approximates to that of invar. The results are discussed in terms of the modern domain concepts of ferromagnetic processes.
