Magnetic Order-Disorder Transition Mediated by a Temperature-Driven Structural Transformation

Abstract

Low energy electron diffraction and magneto-optical Kerr effect measurements were carried out in interleaved mode for epitaxially grown Fe/Cu(100) at temperature variation. What was believed to be a regular thermodynamic Curie transition in 4 monolayer Fe/Cu(100) is shown to be the result of a temperature-driven structural transformation.
