Growth and characterization of minute BaFe12–2xTixCoxO19 crystals from high-temperature solution
Abstract
Minute crystals of barium hexaferrite containing small amounts of
Ti
4+
and Co
2+
ions have been prepared by the slow
cooling method from a high-temperature solution of the
Na
2
O–B
2
O
3
system. Magnetic
properties (coercivity, saturation magnetization, remanence) and lattice
parameters were measured as a function of Ti
4+
and
Co
2+
concentration in the crystals. The site preferences for
Ti
4+
and Co
2+
ions are also discussed.
