摘要: Abstract Mossbauer and magnetization measurements are performed at 300 K on the mixed spinel CoFe2−xCrxO4 with a selective Fe-dilution of B-sublattice increasing Cr concentration X from 0 to 1. Magnetization results for = 1 exhibit collinear ferrimagnetic structure, while indicate that B-sublattice, phase breaks down > 0.8 before reaching percolation limit as result presence competing exchange interactions. These explained in terms Villain's model.
