Single crystals growth of hexaferrits M-type MTixCoxFe₁₂–₂xO₁₉ (M = Ba, Sr) by floating zone and investigation of their magnetic and magnetoelectric properties
Floating zone melting method with optical heating is elaborated to grow single crystals of the substituted hexaferrites BaTixCoxFe₁₂–₂xO₁₉ and SrxTixCoxFe₁₂–₂xO₁₉ (0.8 ≤ x ≤ 2). The dynamics of the growth process is studied and results of the analysis of impurity phases appearing in the initial stag...
