摘要：
The magnetic properties of nanotube are investigated by Monte Carlo simulations. The nanotube is considered as a lattice of spins sigma= +/- 1/2 and S= +/- 1,0. For each block lattice sigma(i) and S-i, the blocking temperature versus values of crystal field is estimated. The magnetization of each spin configuration is computed versus the exchange interaction between the spins of each bloc lattice in the absence and the presence of crystal field at fixed temperature. In addition, the hysteresis cycle for different temperature values in the absence and presence of the crystal field is deduced. (C) 2013 Elsevier Ltd. All rights reserved.
