| Abstract: | Magnetic properties are reported for the spinel series Fe2.4—t Cr0.6Ti t O4, 0≦t≦0.7, with t=0, 0.2, 0.4, 0.6 and Fe2.1—t Cr0.9Ti t O4, 0≦t≦0.55, with t=0, 0.2, 0.4, 0.45, 0.5. Magnetic moment data are compared with theoretical values derived from different ion distribution models. With increasing Ti concentration the compositions become hard magnetic spinels due to the increased number of Fe2+ ions on A- and B-sites of the spinel lattice. |
