Hysteresis behavior of Blume-Capel model on a cylindrical Ising nanotube

We have investigated Blume-Capel model on a cylindrical Ising nanotube by using the effective field theory with correlations. Hysteresis loops, magnetic susceptibility and coercivities have been calculated numerically for ferromagnetic and antiferromagnetic cases. When interactions are low between the core and shell sites, double and triple hysteresis loops can be seen in the system for term- and antiferromagnetic interactions, respectively. The effect of temperature has been examined on hysteresis loops and dependencies of coercivity based on temperature are depicted. (C) 2013 Elsevier Ltd. All rights reserved
