For the ferrites NixCd1-xFe2O4 (x = 0.3, 0.4,...1) the lattice paramet
er, grain size, electrical resistivity, initial permeability, Curie te
mperature and squareness of the magnetization curve were measured. The
results are discussed in terms of the model of the canted spin struct
ure taking into account the domain structure of the polycrystalline fe
rrite.
