Effects of the randomly distributed magnetic field on the phase diagrams of Ising nanowire I: Discrete distributions

Abstract

a b s t r a c tThe effect of the random magnetic field distribution on the phase diagrams and ground state magnetizations of Ising nanowire is investigated using effective field theory with correlations. Trimodal distribution has been chosen as a random magnetic field distribution. The variation of the phase diagrams with that distribution parameters has been obtained and some interesting results have been found such as reentrant behavior and first order transitions. Also for the trimodal distribution, ground state magnetizations for different distribution parameters have been determined which can be regarded as separate partially ordered phases of the system.

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]…”
