Abstract
Within the effective field theory (EFT), the compensation behaviors of mixed spin-1/2 and spin-1 Ising model with transverse crystal field in an external magnetic field are studied on a simple cubic lattice. The model exhibits two types of temperature and magnetic compensation point (Tk and hk) in M−T and M−h space, respectively. At zero or nonzero magnetic field, the single or double Tk is induced by positive transverse crystal field (+Dx/J), but not or only the single Tk in negative crystal field (−Dx/J). The single hk is discovered and adjusted by ±Dx/J. A complex oscillation of magnetization curves at low magnetic field and large ±Dx/J can be observed. The ranges of ±Dx/J which can induce the hk take on an opposite tendency and the oscillation phenomena become weak when the temperature is up. In particular, the influence of transverse crystal field on the temperature and magnetic compensation point is primarily proposed in this work.
