Gd5(SixGe1−x)4 for 0.41⩽x⩽0.5 is orthorhombic and ferromagnetic at lower temperature, monoclinic and paramagnetic at higher temperature, and shows a first order magnetic-structural phase transition between the two. Magnetic moment versus magnetic field (MH) isotherms were measured just above the first order transitiontemperature for Gd5Si1.95Ge2.05 and Gd5Si2Ge2 samples and the field-induced coupled phase transition from paramagnetic/monoclinic to ferromagnetic/orthorhombic phase was observed. Using the method developed by Arrott [Phys. Rev.108, 1394 (1957)], the ferromagnetic portions of the MH isotherms were used to project the second order magnetic phase transitiontemperature of the orthorhombic phase, a region where the transition does not occur due …
