NMR analysis of La+Co doped M-type ferrites

We investigated Sr sub(1-x)La sub(x)Fe sub(12-x)Co sub(x)O sub(19)-powd ers, (an improved variant of the popular hard magnetic M-type hexaferrites SrFe sub(1)2O sub(1)9) with nuclear magnetic resonance at low temperature, and in magnetic fields of up to 3T. Three satellite lines were observed in the...

Zusammenfassung:We investigated Sr sub(1-x)La sub(x)Fe sub(12-x)Co sub(x)O sub(19)-powd ers, (an improved variant of the popular hard magnetic M-type hexaferrites SrFe sub(1)2O sub(1)9) with nuclear magnetic resonance at low temperature, and in magnetic fields of up to 3T. Three satellite lines were observed in the zero-field powder spectra of sub(57)Fe. We assign the satellites to Fe-sites with a f1- and f2-Co neighbors, respectively, and discuss the implications for the total magnetization. copyright 2002 Elsevier Science B.V. All rights reserved.
