ELECTROPHYSICAL PROPERTIES OF NANOSTRUCTURED COMPOSITIONS OF (1-х)АFe12O19 - xBTiO3(A-Ba,Pb,Cd;B-Ba,Pb)

Аннотация

In this work, the electrophysical properties of nanostructured compositions of  (1-х)АFe₁₂O₁₉ - xBTiO₃(A-Ba,Pb,Cd;B-Ba,Pb) ceramics in the range of x=0.0–1.0 with a concentration step Δx=0.1 were studied by complex methods. X-ray difraction revealed that the YbMF compositions in the range of x=0.1–0.5 were hexagonal (H) phase solid solutions. In the concentration range of x=0.6–0.8, the hexagonal and orthorhombic (O) systems coexist, and the unit cell parameters of these phases rise with increasing x. The study of the lattice parameters, bond lengths, bond angles and the main parameters of the magnetic hysteresis loop of the H-phase revealed the presence of a singular point x=0.5 in the concentration range, where extrema of the corresponding parameters were observed.
