Ortiz Física, Astronomía y Matemáticas Mössbauer effect Fe and its alloys Rare earth metals and alloys The magnetic and thermal properties of the Nd2Fe17-xMx (M = Ga, Mn) compounds with 0 < x < 3 have been studied by Magnetic Thermogravimetry (MTG) and Mössbauer Spectroscopy measurements. MTG measurements show that in the M = Mn case Curie temperature increases from T=338 K up to T=341K for x = 0 and 0.2 respectively, while Nd2Fe14Ga3 has a maximum critical temperature of 552 K. The temperature transition decreased with further x increases. On the other hand, the M¨ossbauer spectrum of the Nd2Fe14Mn3 exhibits paramagnetic behavior at room temperature and for Nd2Fe14Ga3a ®-Fe phase was detected. In addition, we analyzed the effect of Ga or Mn substitution in Fe sites on the hyperfine field and quadrupole splitting, where these parameters show a different behavior as a result of substitution of Fe by two different ions as Mn or Ga. 2012 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57030392008 en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
