Many useful ferrimagnetic oxides which crystallize with the spinel structure contain several transition metals, each of which can exist in two or more possible oxidation states. A specific formulation for many such materials is very difficult. An app

Toroids composed of polycrystalline materials of a number of compositions in the system NiFe2O4–Fe3O4–MnFe2O4 exhibit rectangular magnetic hysteresis loops. The squareness ratios, switching coefficients, and coercivities, and their temperature co

The indirect-exchange mechanisms which produce spontaneous magnetization in metal oxides are an optimum if two interacting cations are located on opposite sides of an anion. The coupling rules which have been developed for this case are not applicabl

Crystallographic and magnetic measurements of the system Li+xNi++1−2xNi+++xO for the entire range 0 ⩽ x ⩽ 0.5 are reported. For values ofx ⩽ 0.3, the lattice appears to be antiferro-magnetic and is cubic above the Curie temperature. For the r
