JOURNAL OF SUPERCONDUCTIVITY AND NOVEL MAGNETISM
The mixed spin-1 and spin-3/2 Ising system is investigated on the Bethe lattice at random distribution of crystal field which are taken equal at both spin sites. The investigations of thermal variations of the sublattice, net and average magnetizations have revealed that the system gives three compensation temperatures in contrary to the literature where only two of them are mentioned so far. The phase diagrams of the random crystal field case with probability p are also calculated at the range of 0 ae p < 1.0. It is found that in this range for equal crystal field case, the tricritical points disappear and only the second-order phase transitions are exhibited which is opposite to the case p = 1.0. In addition, we have also classified the thermal variations of average magnetizations according to the N,el nomenclature.
