摘要：
The magnetic properties of a mixed spin-3/2 and spin-2 and a mixed spin-3/2 and spin-5/2 Ising ferromag-netic system with different anisotropies are studied by means of mean-field theory(MFT).The dependence of the phasediagram on single-ion anisotropy strengths is studied too.In the mixed spin-3/2 and spin-2 Ising model,besides thesecond-order phase transition,the first order-disorder phase transition and the tricritical line are found.In the mixedspin-3/2 and spin-5/2 Ising model,there is no first-order transition and tricritical line.
