Abstract
A two-sublattice decorated Blume-Capel ferrimagnet has been investigated
using the mean field theory. Interesting behaviors of long-range order
are obtained depending on particular magnitudes of magnetocrystalline
anisotropies for both sublattices sites. Distinguishable features have
been discovered in two-dimensional decorated lattice consisting of
spin-5/2 and decorating spin-7/2 ions on the bonds. It is found the
present system shows two ferrimagnetic compensation temperatures.
However, one compensation temperature for different or fixed values of
decorated magnetic anisotropies with the values of J1=-0.5 , J2=-1.0 ,
or with J1=-1.0 , J2=-0.5, has been induced, respectively. The
magnetization behavior in the (M,DB/IJ2I) space has not already been
considered showing the crystalline anisotropy dependence of total
magnetization remanences. Besides, the variations of net magnetizations
versus the decorated crystal fields, i.e., in the(M,DA/IJ2I) space, have
been done, with J1=-0.5, J2=-1.0 , for various values of T=2.0, 2.5,3.0
, respectively.
