Structure, hyperfine interactions and magnetization studies of mechanically alloyed Fe50Ge50 and Fe62Ge38

Structure and anelasticity of Fe3Ge alloy

“…The b phase is thermodynamically stable in a wide range of temperatures. The Curie temperatures for the b phase given in the literature vary from T C ¼ 430 K in Fe-50Ge [26] over T C ¼ 485 K in Fe37Ge [27] to T C ¼ 500 K in Fe-35Ge [28]. Our own test of Fe-37 at.%Ge gives a value of T C ¼ 505 K. A decrease of T C with increasing Ge content in FeeGe b alloys was also shown by Kanematsu [28] (from 500 K for Fe-35Ge to 150 K for Fe43Ge) and by Konygin et al [12] (from 480 K for Fe-35Ge to 400 K for Fe-40Ge).…”

Cubic, hexagonal and tetragonal FeGex phases (x = 1, 1.5, 2): Raman spectroscopy and magnetic properties

“…On the other hand, monoclinic FeGe phase possesses a complex magnetic structure with an overall antiferromagnetic behaviour 9 . Most of the iron-rich compounds with hexagonal (B8 2 ) β or η-Fe x Ge (1.32 < x < 1.67) structure exhibit a ferromagnetic nature [10][11][12] . Apart from interesting magnetic properties 13,14 , Fe 2 Ge 3 has been studied for its high thermoelectric performance 15 .…”

Thermal stability and hyperfine interactions of mechanically alloyed Fe–Ge phases

“…Moreover, a very few papers concerning hyperfine interactions in the mechanically alloyed Fe-Ge phases have appeared in the modern literature [2][3][4][5][6][7].…”
