Magnetic, transport, and structural properties of SrRuO3 thin films
(2014)
Thin films of the oxide ferromagnetic metal SrRuO3 (SRO) are studied, in view of their potential use within oxide-based spin electronic devices. Here, their epitaxial growth on Si-compatible SrTiO3 substrates is demonstrated ...
Magnetization processes in micron-scale (CoFe/Pt)(n) multilayers with perpendicular anisotropy: First-order reversal curves measured by extraordinary Hall effect
(2012)
First-order reversal curves (FORCs) were recorded using the extraordinary Hall effect in micron-sized crosses of [Co90Fe10 (0.5?nm)/Pt (1.0?nm)] n multilayers with n?=?10, 20, and 50, which exhibit perpendicular magnetic ...
High spin polarization in epitaxial films of ferrimagnetic Mn3Ga
(2011)
Ferrimagnetic Mn3Ga exhibits a unique combination of low saturation magnetization (Ms=0.11 MA m−1) and high perpendicular anisotropy with a uniaxial anisotropy constant of Ku = 0.89 MJ m−3. Epitaxial c-axis films exhibit ...
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 ...
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 ...
Giant spontaneous Hall effect in zero-moment Mn2Ru x Ga
(2015)
Spin-dependent transport properties of Mn2Ru x Ga thin-films are studied as function of the Ru concentration and the substrate-induced strain. The large spontaneous Hall angle of 7.7% twenty times bigger than in other 3d ...
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 ...
Site-specific order and magnetism in tetragonal Mn3Ga thin films
(2013)
Mn

Ga bulk material and thin films deposited on several different substrates have been investigated using
x-ray and neutron diffraction, x-ray absorption spectroscopy, x-ray magnetic circular dichroism, and ...
Cubic Mn 2 Ga Thin films: Crossing the spin gap with ruthenium
(2014)
Cubic Mn2Ga films with the half-Heusler C1b structure are grown on V (001) epitaxial films. The phase is a soft ferrimagnet, with Curie temperature TC = 225 K and magnetization Ms=280 kA m−1, equivalent to 1.65μB per ...
