Competing anisotropies and first-order magnetization processes in (Zn,Co)W-type hexaferrite.

Focuses on the magnetic properties of a W-type hexaferrite showing first-order magnetization processes in order to verify whether the same model can be applied to these different materials. Magnetic properties of barium and cobalt crystals; Use of a vibrating sample magnetometer with cryostat; Relation between applied and internal fields in an ellipsoid.
