STRUCTURAL, MAGNETIC AND MOSSBAUER STUDIES OF A NEW EQUIATOMIC EU-BASED STANNIDE - EUAGSN

We report here our results on a new intermetallic compound, EuAgSn. X- ray diffraction studies of the material show that it forms in the orth orhombic-type structure. Magnetic susceptibility results show that the material orders magnetically at similar to 6.5 K. The temperature dep endence of the paramagnetic susceptibility follows a Curie-Weiss behav iour with an effective moment close to that of the free Eu2+ ion. Eu-1 51 and Sn-119 Mossbauer studies confirm the magnetic ordering. The (15 1)EU isomer shift (similar to - 11 mm/s) is consistent with the stable divalent state of Eu in this material.
