Tunneling anisotropic magnetoresistance of NiFe/IrMn/MgO/Pt stack: An antiferromagnet based spin-valve
anisotropic magnetoresistance NiFe/IrMn/MgO/Pt stack
2010/11/22
Spin-valve is a microelectronic device in which high and low resistance states are realized by utilizing both charge and spin of carriers. Spin-valve struc-tures used in modern hard drive read-heads a...
Local electronic structure of Fe$^{2+}$ impurities in MgO thin films: Temperature-dependent soft x-ray absorption spectroscopy study
Local electronic structure of Fe$^{2+}$ impurities Temperature-dependent soft x-ray absorption spectroscopy study
2010/11/18
We report on the local electronic structure of Fe impurities in MgO thin films. Using soft x-ray absorption spectroscopy (XAS) we verified that the Fe impurities are all in the 2+ valence state.The fi...
