Balcells, Ll. ; Beltrán Finez, Juan Ignacio ; Martínez-Boubeta, C. ; Konstantinovi?, Z. ; Arbiol, J. ; Martínez, B. | American Institute of Physics | 2010-12-20In this work we report on the magnetic behavior of MgO thin films prepared by sputtering. A severe aging process of the ferromagnetic properties is detected in magnetic samples exposed to ambient atmosphere. However, ferromagnetism can be succes[...]texto impreso
Martínez-Boubeta, C. ; Beltrán Finez, Juan Ignacio ; Balcells, Ll. ; Konstantinovi?, Z. ; Valencia, S. ; Schmitz, D. ; Arbiol, J. ; Estrade, S. ; Cornil, J. ; Martínez, B. | American Physical Society | 2010-07-08We show both theoretical and experimental evidences of the appearance of ferromagnetism in MgO thin films. First principles calculations allow predicting the possibility of the formation of a local moment in MgO, provided the existence of Mg vac[...]
