Mössbauer spectral and magnetic investigations of RFe10Cr2 compounds (R=rare earth)

Investigation of structural stability and site preference of Dy(Fe,T)12 and Dy(Fe,T)12Nx (T=Ti, V, Cr, Nb, Mo)

“…With these pair potentials, we also calculated the equilibrium lattice constant of Dy(Fe,T) 12 and their nitrides. The results in Table 1 indicate that, upon nitrogenation, the tetragonal structure is retained with an increase in lattice parameters, and that the present calculations accord with the experimental observation [36][37][38][39].…”

An investigation of the Dy–Fe–Cr phase diagram: Phase equilibria at 773K

“…Bara et al and Courtois [9,10] reported the existence of two ternary compounds, namely DyFe 12−x Cr x and Dy 3 Fe 29−x Cr x . The samples were prepared by arc-melting the high purity (99.9%) constituents in argon atmosphere.…”

Isothermal section of the Y–Fe–Cr ternary system at 773K

“…The magnetic properties of the ternary compounds of R(Fe,M) 12 and R 3 (Fe,M) 29 have been investigated intensively [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. In both the compounds, the presence of a third element M (M = Ti, V, Cr, Mn, Nb, Mo, W, etc.)…”

“…Two ternary compound of the Y-Fe-Cr system, i.e. YFe 10 Cr 2 and Y 3 (Fe,Cr) 29 have been found in literature [2,9,10]. Investigations on the compound YFe 10 Cr 2 were available in Refs.…”

“…Investigations on the compound YFe 10 Cr 2 were available in Refs. [2,9]. The phases of Y 2 Fe 17 (with Th 2 Ni 17 -type structure), YFe 10 Cr 2 (with ThMn 12 -type structure) and Y 3 (Fe,Cr) 29 (with Nd 3 (Fe,Ti) 29 -type structure) can be derived from the basic hexagonal CaCu 5 -type structure by the replacement of 1/3, 1/2 and 2/5 of the Y atoms by a pair of Fe atoms (known as dumb-bell atoms), where Y and Fe occupy the Ca and Cu sites, respectively.…”
