The scaling approach allows finding the dependence of Hexch on T or higher powers of M, which determine the order of the phase transition. Within the thermodynamics of the mean-field theory, the magnetocaloric effect is obtained, in a straightforward way, from the magnetic equation of state. Results are presented for first- and second-order magnetic phase transitions in manganites and metastable nanocrystalline metal alloy.<\/jats:p>","DOI":"10.1063\/1.2801692","type":"journal-article","created":{"date-parts":[[2007,10,22]],"date-time":"2007-10-22T20:52:15Z","timestamp":1193086335000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":79,"title":["A mean-field scaling method for first- and second-order phase transition ferromagnets and its application in magnetocaloric studies"],"prefix":"10.1063","volume":"91","author":[{"given":"J.
