Abstract

We studied the parameters of the effective magnetic anisotropy of system of hexaferrite nanocrystals of composition Ca0.5Ba0.5Fe12O19 with an average size 35 nm at 300 K. The constant the field of effective magnetic anisotropy determined from the magnetization curves using five different methods. It was shown that the substitution of ions Ba2+ by ions Ca2+, while maintaining the magnetic matrix, the constant Кaef reduced by more than half in comparison with unsubstituted composition powder of the same dispersion.
