“…The S J and C J are the interaction parameters between two nearestneighbor magnetic atoms at the surface shell and core, respectively, and 1 J is the interaction parameters between two nearest-neighbor magnetic atoms at the surface shell and the core. In order to clear up of the surface effects on the physical properties of the system, S J surface interaction parameter is often defined as [25,29,32,34]. According to the framework of EFT, we can easily obtain C m magnetization at the core and S m magnetization in the shell surface for the HIN system depicted in Fig.…”

By means of the effective-field theory (EFT) with correlations, the thermodynamic and magnetic quantities such as magnetization, susceptibility, internal energy, free energy, hysteresis curves and compensation behaviors of the spin-1/2 hexagonal Ising nanowire (HIN) system with core/shell structure have been presented. The hysteresis curves are obtained for different values of the system parameters on both ferromagnetic and antiferromagnetic case. It has been shown that the system only undergoes a second-order phase transition. Moreover, from the thermal variations of the total magnetization, the five compensation types can be found under certain conditions, namely the Q-, R-, S-, P-, and N-types.

“…The magnetization and susceptibility of a cylindrical core/shell spin-1 Ising nanowire was theoretically investigated within the effective field theory, with correlations for both ferromagnetic and antiferromagnetic exchange interactions between the shell and the core (Sarli and Keskin, 2012). The magnetization reversal processes were observed as peaks in the susceptibility versus switching field curve defining the Figure 9.14 Hysteresis loops of three nickel (Ni)/iron oxide core/shell samples defined by different geometries at 5 K (a) and 300 K (b).…”

In this paper, we investigated local spin orientation (up or down) effects on magnetizations of the monolayer nanographene by using effective field theory developed by Kaneyoshi. It is found that the monolayer nanographene and its components have very small magnetization (mC1≈mC2≈mC3≈mMLNG≈2.31x10-18≈0) at T≈0.00 for the Jd1<0 (C1-spin up, C2-spin down and C3-spin up). On the other hand, for Jd2<0, Jd3<0, Jd4<0, and Jd5<0, the monolayer nanographene and its components (C1, C2 and C3 atoms) have very large local spin induced magnetization (mC1≈mC2≈mC3≈mMLNG≈1;1>>2.31x10-18) than those of the Jd1<0. These results clearly indicate that the local spin orientation in the monolayer nanographene has very strong effect on its magnetism.
