Hysteresis loops and susceptibility of a transverse Ising nanowire

In this work, the magnetization, susceptibility, and hysteresis loops of a magnetic nanowire are described by the transverse Ising model using the effective field theory within a probability distribution technique. The effects of the exchange interaction between core/shell and the external fields on the magnetization and the susceptibility of the system are examined. Some characteristic phenomena are found in the thermal variations, depending on the ratios of the physical parameters in the shell and the core.

► We use the effective-field theory with a probability distribution technique to investigate.
► The magnetic properties of a magnetic nanowire in the presence of both the longitudinal and the transverse field.
► Triple hysteresis loop patterns for magnetic nanowire are observed which may have potential in producing a multi-state memory.
► Our theoretical predictions may be a reference for future experimental studies on the magnetic nanowire.
