Physical Review Letters 76, pp 4620-4623 (1996) 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.
