“…The magnetic properties of Laves phase compounds between rare-earth metal (R) and 3d transition metal (M) have been extensively investigated because of the full variety of magnetism. Especially the R(Fe 1-x Mn x ) 2 compounds have very interesting magnetic properties [2][3][4][5][6]. A series of studies have been conducted by Ilyushin et al to determine the phase relations in the RFe 2 -RMn 2 pseudo-binary systems, with R= Er, Ho, Gd, Tb and Dy, and to determine the effect of composition on the magnetic properties of the R(Fe 1-x Mn x ) 2 compounds [7][8].…”

The crystal structure of GdFeMn alloy has been investigated by using X-ray powder diffraction (XRD) followed by Rietveld refinement technique, differential thermal analysis (DTA) and scanning electron microscopy (SEM) equipped with energy dispersive X-ray spectroscopy (EDS) techniques. XRD results showed that annealed GdFeMn alloy was a single phase of Gd6(Fe0.5Mn0.5)23 compound, with Th6Mn23-structure. SEM/EDS results and Rietveld refinement revealed that GdFeMn alloy was not really a new ternary compound as reported, but a solid solution Gd6(Fe0.5Mn0.5)23 which was only a point between Gd6Fe23 and Gd6Mn23. It was also found from DTA measurement that a reaction, Gd (Fe0.5Mn0.5)2 → liquid (rich Gd) + Gd6(Fe0.5Mn0.5)23, had taken place above 650.81 oC, and the educed Gd existed in educed part of GdFeMn sample. The results demonstrated the real structure of the GdFeMn compound as reported was Gd6(Fe0.5Mn0.5)23 compound.

Large Magnetocaloric Effect in Laves Phase TbMn 1.8 Fe 0.2 Compound over a Wide Temperature Range. -The title compound is characterized by magnetization and heat capacity measurements. TbMn1.8Fe0.2 exhibits a large magnetocaloric effect over a wide effective temperature range, related to a second-order magnetic Tb-Tb sublattice ordering transition at its Curie temperature of about 80 K. The compound does not show hysteresis effects, is easy to synthesize, and exhibits high chemical and physical stabilities, which suggests that the material is a promising candidate for magnetic refrigeration applications in the temperature range 45-120 K. -(GAO*, T.; NISHIMURA, K.; LI, L.; NAMIKI, T.; ISIKAWA, Y.; J.
