| Abstract: | A series of SrBa ferrites with composition (Sr0.75Ba0.25)1-x(La2O3) x/2 · 5.3Fe2O3 has been prepared by the conventional ceramic technology. The size of the crystallites corresponds to that of a single magnetic domain. Doping of La not only enhances the coercivity of these materials but also improves the remanence. The reasons for improving the hard magnetic properties of the investigated ferrites are discussed. © 2002 Elsevier Science B.V. All rights reserved. |
