Özet

Physical properties of the Sm 1-x Gd x Ni 4 B (0 ≤ x ≤ 1.0) compounds have been investigated by means of the X-ray powder diffraction, AC susceptibility techniques. All the compounds studied crystallize in CeCo 4 B type structure with P6/mmm space group. The substitution of Gd for Sm leads to a decrease of the unit-cell parameters a and the unitcell volume V, while the unit-cell parameter c remains almost constant. Magnetic measurements present the visible magnetic phase transition, around definite transition temperatures. The magnetic phase transition temperatures are found at the temperature where the maximum of χ ac (T) occurs. We have obtained the transition temperatures for the samples x = 0.0, 0.2, 0.4, 0.6, 0.8 and 1.0 as 39, 37.77, 37.22, 36.75, 35.74, and 35.1 K, respectively. © Springer Science+Business Media, LLC 2010.
