Abstract

In this work, the hysteresis behavior of the nanotube, consisting of a ferromagnetic core of spin-1 surrounded by a ferromagnetic shell of spin-1 with anti-ferromagnetic interfacial coupling is studied in the presence of a random magnetic field. Based on a probability distribution method, the effective field theory has been used to investigate the effects of the random magnetic field, the interfacial coupling constant and the shell coupling on the hysteresis loops of the nanotube. Some characteristic behaviors have been found..
