| Abstract: | Electron spin resonance study has been carried out on melt-spun ribbon of Ni(55)Mn(19.6)Ga(25.4) exhibiting coupled magnetostructural transition. The correlation of electron spin resonance, thermal and magnetic results permitted a clear distinction of various phases and their transformations. Both structural and magnetic transitions coexist in the temperature range 300 <= T <= 310 leading to four different magnetic phases namely paramagnetic austenite, ferromagnetic austenite, paramagnetic martensite, and ferromagnetic martensite. The sample exhibits a single paramagnetic austenite phase above 310 K while it shows a ferromagnetic martensite phase below 260 K. (C) 2009 [DOI: 10.1063/1.3148863] |
