We report the structural characterization of Gd5Ge2(Si1 − xSnx)2 (x = 0.23 and x = 0.40) compounds by means of 100 and 298 K-X-ray diffractometry (XRD) and 4 K-155Gd and 298 K-119Sn Mossbauer spectroscopy. These compounds order ferromagnetically at

In this work we report the observation of weak ferromagnetism in the hexagonal C14 Laves phase (s.g. P63/mmc) of the (Fe1–xNix)2Nb system, which has been reported as nonmagnetic in the literature. A larger unit cell volume is observed as compared t

In this work are studied the structure and magnetic properties of the (Fe 1− x Co x ) 2 Nb alloys with X-ray diffraction and magnetization measurements. The results confirm the formation of the C14 Laves phase in the Co concentration range 0 ≤ x

We report a study about the structural properties of polycrystalline samples of nominal composition Gd 5 Ge 2 (Si 1− x Sn x ) 2 ( x =0.23, 0.40) that closely influence their physical behavior particularly related to electric resistivity and magneto

The Fe-Nb system was investigated by means of X-ray diffraction and Mossbauer spectroscopy (at 300 and 77 K), in the range from 1 to 66.7 at%. We have found that the limit of solubility of Fe in Nb at 1100°C is between 3 and 4 at% Fe, and observed t

The effects on the structure and magnetic properties of the phases in (Fe1−xCox)0.875Nb0.125 alloys due to the replacement of Fe by Co are studied by 57Fe Mossbauer spectroscopy, X-ray diffraction, electron probe microanalysis and vibrating sample
