The blocking temperature of an amorphous cylindrical nanowire of length L and radius R is studied within the framework of Monte Carlo simulation based on Metropolis algorithm. The nanowire is formed by alternate layers of atoms A and B. The interlayer coupling JAB is ferromagnetic. The effects of the exchange couplings JB and JAB, the plane anisotropy Dxy, and the amorphization α on the blocking temperature of the system are investigated. We found that the blocking temperature increases with increasing the value of the exchange couplings JB and JAB and decreases with increasing the plane anisotropy Dxy and the degree of the amorphization α.
