The nanosized monolayer is divided into the core, core-surface, and surface parts as introduced in J. Mugn. Magn. Mater. 373, 217 (2015). The dipolar (or magnetization M) and quadrupolar (Q) order parameters are calculated. We have investigated M vs. magnetic field H behaviors for different values of L, temperatures T, and monolayer sizes R. We also observed Q-D, M-D and Q-H hysteresis loops. These results are discussed in relation to other theoretical findings.eninfo:eu-repo/semantics/openAccessEmery-Griffiths ModelMulticritical Phase-DiagramsMagnetic-PropertiesMonte-CarloAustenitic TransformationsApproximationEquilibriumTransitionSeparationBehaviorsArticle1401849010.12693/APhysPolA.140.842-s2.0-85113837639Q4WOS:000697365900013Q4
