Effects of the trimodal random field on the magnetic properties of a spin-1 Ising nanotube

Abstract

In this work, the hysteresis behavior of a nanotube, consisting of a ferromagnetic core of spin-1 atoms surrounded by a ferromagnetic shell of spin-1 atoms with ferro- or anti-ferromagnetic interfacial coupling is studied in the presence of a random magnetic field. Based on a probability distribution method, the effective-field theory has been used to investigate the effects of the random magnetic field, the interfacial coupling constant, and the temperature on the hysteresis loops of the nanotube. Some characteristic behaviors have been found, such as the existence of double or triple hysteresis loops for appropriate values of the system parameters. The remanent magnetization and the coercive field, as functions of the temperature, are examined.

Hysteresis and compensation behaviors of spin-3/2 cylindrical Ising nanotube system

“…Canko et al [30] examined thermodynamic properties of spin-1 Ising nanotube. Magoussi et al are examined the hysteresis behaviors [31], and phase diagrams and magnetic properties [32] of a spin-1 Ising nanotube. Furthermore, Jiang et al [33] studied spin-3/2 core and a hexagonal ring spin-5/2 shell by the EFT with self-spin correlations.…”

“…On the other hand, effective field theory developed by Kaneyoshi, which successfully identifies many magnetic nanosystems such as nanoparticles, thin films, nanowires and nanotubs [30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47] and enables the magnetic properties of these nanosystems to be successfully obtained, modeling nanosystems, it has emerged as a successful theoretical method which is used for defining and examining magnetic systems and applied continuously to different nanosystems. For example, using the effective field theory, the magnetic properties of the cubic nanowire [48], the hexagonal Ising nanowire [49], the mixed Ising nanoparticles [50], the spin-1 Ising nanotube [51], cylindrical transverse spin-1 Ising nanowire [52], cubic nanowire [53], a kinetic cylindrical Ising nanotube [54], honeycomb thin film [55], diluted transverse Ising nanowire [56], core/shell nanowire system [57], a mixed core/shell nanotube [58], core/shell spin-1…”

Spin-1 Tek Boyutlu Ising Sisteminin Manyetik Özellikleri

“…Recently, the EFTdeveloped by Kaneyoshi has been used in the theoretical investigation of the magnetic features of the nanostructures [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20], due to the description of the lowdimensional systems is very easily applied by using EFT and the theoretical results of that system obtained by EFT are in good consistent with the other theoretical and experimental findings of low-dimensional systems. Such as, magnetic features of the Ising nanowire [21][22][23][24][25][26][27][28][29][30][31][32], core/shell Ising nanostructures [33][34][35], Ising nanotube [36,37], Ising thin film [38], Ising nanolattices [39], Ising nanographene [40] and onedimensional Ising system (1DIS) [41] were worked by using effective field theory. Although the EFT is commonly widely used for the examinations of the magnetic features of the low-dimensional system and its theoretical findings are in good consistent with the experimental results of that system, there is only one work reported by Şarlı [41]…”
