Evidence of antiferromagnetic phases in discontinuous Fe/CaF2 multilayers
Source abstract
Abstract
Abstract Detailed measurements of the field and temperature dependence of the magnetization of composite thin Fe/CaF 2 multilayers are presented. It was found that the magnetic irreversibility occurs mainly due to frustration of the antiferromagnetic interactions in a magnetic structure consisting of Fe fluorides embedded in a CaF 2 matrix. Our results show that the many interfaces between Fe and CaF 2 in multilayers promote a chemical reactivity leading to Fe 3+ antiferromagnetic compounds.
