Alloys of Ho 1− x Tb x Fe 1.95 ( x =0, 0.15, 0.25, 0.5, 0.75 and 1) were prepared and investigated for structural and magnetic properties. The microstructure of the alloys investigated consists of three phases viz. RFe 2 as major phase, RFe 3 and R-rich as minor phases. The RFe 3 phase, however, appears in minimum volume fraction for concentrations up to x

Structural, magnetic and Mössbauer studies on magnetostrictive Ho1―xTbxFe1.95 [x = 0-1]

Magnetic and electrical transport studies have been carried out on Ho0.85Tb0.15Fe2-xMnx[x=0-2] in the temperature range 5-300 K. The saturation magnetization at 5 K is found to increase with increasing Mn content due to the absence of Mn moments. The temperature variation of magnetization reveals several spin reorientation transitions and these are compared with the ac susceptibility results. Electrical resistivity reveals the dominance of electron magnon scattering at low temperatures and electron-phonon scattering at high temperatures
