Tunneling processes in asymmetric double barrier magnetic tunnel junctions with a thin top MgO layer
(2013)
Dynamic conductance dI/dV and inelastic electron tunneling spectroscopy (IETS) d 2I/dV 2 have been measured at different temperatures for double barrier magnetic tunnel junctions with a thin top MgO layer. The resistance ...
Magnetic and electronic properties of D022-Mn3Ge (001) films
(2012)
Oriented thin films of Mn3Ge with the tetragonal D022structure,grown on strontium titanate substrates, exhibit a low magnetization M s?=?73?kA m?1 combined with high uniaxial anisotropyK u?=?0.91?MJ m?3 at 300?K, making ...
Site-specific magnetism of half-metallic Mn2RuxGa thin films determined by x-ray absorption spectroscopy
(2015)
The site-specific magnetic properties of thin films of the Heusler compound Mn2RuxGa, 0.6 <x< 1.0, are
studied using x-ray absorption and dichroism spectroscopy. There is evidence of half metallicity up to x = 0.7,
and ...

The zero-magnetization Heusler ferrimagnet
(2013)
An unusual zero-moment half-metallic state has been predicted in stoichiometric Heusler compounds with 24 valence electrons, where, unlike an antiferromagnet, the two sublattices are chemically or crystallographically ...
Ferromagnetism in defect-ridden oxides and related materials
(2010)
The existence of high-temperature ferromagnetism in thin films and nanoparticles of oxides containing small quantities of magnetic dopants remains controversial. Some regard these materials as dilute magnetic semiconductors, ...
Exchange-biased magnetic tunnel junctions with antiferromagnetic epsilon-Mn3Ga
(2012)
Oriented c-axis films of the hexagonal triangular antiferromagnetic ?-Mn3Ga have been used in bottom-pinned synthetic antiferromagnetmagnetic tunnel junctions with MgO barriers, which show up to 150% tunneling magnetoresistance ...

Origin of the Two-Dimensional Electron Gas at LaAlO3=SrTiO3 Interfaces: The Role of Oxygen Vacancies and Electronic Reconstruction
(2013)
The relative importance of atomic defects and electron transfer in explaining conductivity at the crystalline LaAlO3=SrTiO3 interface has been a topic of debate. Metallic interfaces with similar electronic properties ...
