Resumen

CAFFARENA, V. T.; OGASAWARA, T.; PINHO, M. S.  y  CAPITANEO, J. L.. Samarium-iron garnet nanopowder obtained by co-precipitation. Lat. Am. appl. res. [online]. 2006, vol.36, n.3, pp. 137-140. ISSN 0327-0793.

In this work, samarium-iron garnet nanopowder (Sm3Fe5O12) was obtained and characterized by TG/DTA, XRD, SEM and EDS. The synthesis of this magnetic material was carried out by the co-precipitation method, using hydrated chlorides of the rare-earth elements and ferrous sulfate. PVA was added to the calcined powder in order to facilitate the production of a toroidal compact specimen, which was submitted to sintering in the range of 1200 oC to 1400 oC, to stablish a correlation of its magnetic properties with morphology.
