Equilibrium current temperature quasi-oscillations in a ferromagnetic loop

arXiv:cond-mat/0307128 · doi:10.1016/j.jmmm.2003.12.996

Abstract

Equilibrium persistent current carried by a small ferromagnet-metal loop is considered. This current is shown to be quasi periodic in temperature at low temperatures. The quasi period is determined mainly by the temperature dependence of the magnetization.
