Nanosized monolayer on the square lattice within spin-1 ising Model: Hysteretic properties with odd interactions

Abstract

We propose a theoretical framework for the investigation of M-H and Q-D hysteresis loops for the nanosized monolayer on the square lattice within spin-1 Ising model Hamiltonian with dipolar (J), quadrupolar (K), dipolar-quadrupolar (odd, L) interactions and single-ion anisotropy parameter (D) in pair approximation. We observed that the shift of these loops depends on K, D, temperature (T) and monolayer size (R). These are also discussed in relation with the experimental and theoretical findings.
