The magnetic properties of a decorated Ising nanotube examined by the use of the Monte Carlo simulations

•Critical behaviors in the decorated Ising nanotube are examined by the MCS.•Phase diagrams and total magnetizations are obtained.•The blocking temperature is obtained for different values of crystal field.•The remanence and coercive field are obtained.

The magnetic properties of nanotube are investigated by Monte Carlo simulations. The nanotube is considered as a lattice of spins σ=±1/2 and S=±1,0. For each block lattice σi and Si, 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.
