The formation of Co magnetic moment in the paramagnetic phase of GdCo 2 has been studied by means of first principles calculations. The introduction of impurities in the transition metal-rare-earth Laves phases leads to changes in the density of stat

Complex perovskite materials with the A2BB′O6 formula have been recently studied because of their peculiar magnetic and electronic properties. The origin of magnetism in the double perovskite Sr2FeMoO6 brought these properties again into discussion

We report several ab initio calculations performed over the A2FeMoO6 (A=Ba, Ca) double perovskite. Results show that it is an insulator for the spin up orientation and conductor for the other one. We investigate the electronic structure of A2FeMoO6 b

Zero-field muon spin relaxation spectroscopy (μSR) measurements in the paramagnetic phase of ErCo2 ferrimagnetic system are reported. Previous experimental studies using macroand microscopic techniques led to the identification of magnetic short-ran
