Site-selective cobalt substitution in La–Co co-substituted magnetoplumbite-type ferrites: 59Co-NMR and DFT calculation study
The La–Co co-substituted magnetoplumbite-type (M-type) ferrites A Fe _12 O _19 ( A = Ca, Sr and Ba, ion sizes Ca ^2+ $\lt$ Sr ^2+ $\lt$ Ba ^2+ ) with Co compositions around 0.2 have been subjected to ^59 Co-NMR. The results show that Co occupies the 4f _1 , 2a and 12k sites, and that the smaller the...
