Hysteretic dipolar and quadrupolar properties of the spin-1 Blume-Emery-Griffiths model under pair approximation

As a continuation of previously published work [A. Erdinc and M. Keskin, Int. J. Mod. Phys. B 18, 1603 (2004), doi:10.1142/S0217979204024823] the hysteretic properties of magnetization (m) and quadrupolar moment (q) have been investigated for the spin-1 Blume-Emery-Griffiths model using pair approximation. The magnetic field (h) dependence of m is produced for different values of the lattice coordination number (z), biquadratic interaction (k) and single-ion anisotropy (d). The (m,h) loops show different and novelty properties when d < 0. We also observed the hysteresis cycles in the (q,d), (q,h) and (m,d) planes. These curves strongly depend on biquadratic interaction k. Our results are found to be in good agreement with the other theoretical findings.

Automated summary

In this study, the hysteresis properties of magnetization and quadrupolar moment for the spin-1 Blume-Emery-Griffiths model were investigated using pair approximation, with a focus on the effects of lattice coordination number, biquadratic interaction, and single-ion anisotropy. The results showed novel properties in the (m,h) loops when d < 0, and hysteresis cycles were observed in various planes. These properties strongly depend on the biquadratic interaction k, and the findings are consistent with other theoretical studies.
