Composition And Temperature Dependences In Ising-Type Multisegment Nanostructure

Abstract

In the present study, an Ising-type multisegment nanowire (IMN) with ferromagnetic / non-magnetic segment structure is investigated by means of the effective-field theory (EFT) with correlations. The effects of the composition (p) and temperature (T) on the magnetic hysteresis properties are investigated in detail. The coercive field (HC) and squareness (Mr /MS) of the IMN is also derived from hysteresis loops as a function of p and T. In this system, it was found that the p and T have a significant effect on the magnetic behavior. When the obtained theoretical results compare with some experimental works of nanowire in view of hysteresis behaviors, a very good agreement between them is observed.
