Monte Carlo simulation study for hysteresis properties of a Prussian blue analog nanowire

We have studied the hysteresis loops and hysteresis related properties (like coercivity, remanence and saturation magnetization) of a cylindrical ternary alloy Prussian blue analog nanowire of the type AB(x)C(1-x) by means of Monte Carlo simulations. We consider a ferromagnetic coupling between type-A and and type-B magnetic components (J(AB) > 0) and an antiferromagnetic coupling between type-A and and type-C magnetic components (J(AC) < 0). By defining exchange interaction ratio, R = vertical bar J(AC)vertical bar/J(AB), we have shown that for special values of R and concentration x, nanowire displays a minimum value of coercive field which is attributed to the existence of compensation behavior in the system. Moreover, minimum values of remanent magnetization are observed for x values at which the positive and negative magnetization components are about to balance each other. Finally, temperature dependence of coercivity and remanence are investigated in a wide temperature range.
