Finite temperature magnetic phase transition features of the quenched disordered binary alloy cylindrical nanowire

Thermal and magnetic phase transition properties of a quenched disordered binary alloy cylindrical nanowire of the type ApB1−p have been elucidated by making use of Monte Carlo simulation based on a local spin update Metropolis algorithm. Magnetic components A with spin-½ and B with spin-1 are distributed randomly throughout the cylindrical nanowire with a probability of p and 1−p, respectively. The phase boundary lines, magnetization and also magnetic susceptibility profiles of the system in both presence and absence of a single-ion anisotropy term are investigated. Our Monte Carlo simulation results indicate that the critical behavior of the system sensitively depends on the concentration value of the type-A atoms, the spin-spin exchange interaction strength between unlike magnetic components as well as on the single-ion anisotropy interaction. Finally, a comparison of our observations with those of recently published studies for the clean cylindrical nanowire systems corresponding to p = 0.0 and p = 1.0 cases is presented and it is found that there exist satisfactory agreements.
