High inverted tunneling magnetoresistance in MgO - based magnetic tunnel junctions
(2007)
Inverted tunneling magnetoresistance, where resistance decreases as the free layer in a magnetic tunnel junction flips its direction of magnetization after saturation, has been observed at zero bias in magnetic tunnel ...
Gas-phase interstitial modification of rare-earth intermetallics.
(IEEE, 1992)
The gas-phase interstitial modification of rare-earth intermetallics is studied. Net reaction energies for nitrogen in Sm2Fe17 and Nd(Fe11Tl) are U 0=-57 kJ/mole and U0=-51 kJ/mole, respectively. The equilibrium nitrogen ...
Raman spectroscopy of ferromagnetic CrO2
(American Physical Society, 1999)
Polarized Raman spectra of the ferromagnetic metal CrO2 were measured in a broad temperature range
including Tc'390 K. The Raman-allowed modes of A1g , B1g , B2g , and Eg symmetry were identified and
compared to the ...
Magnetization of a Dy(Fe11Ti) single crystal
(American Physcial Society, 1990)
Magnetization curves have been measured in the temperature range from 4.2 to 300 K along the [100], [110], and [001] directions of a Dy(Fe11Ti) single crystal in fields up to 7 T. The magnetic moment is along [100] below ...
Bias voltage dependence of inverted magnetoresistance on the annealing temperature in MgO-based magnetic tunnel junctions
(Elsevier, 2009)
MgO-based magnetic tunnel junctions (MTJs) with a layer sequence Ir22Mn78 or Fe50Mn50 (10 nm)/CoFe (2 nm)/Ru (0.85 nm)/CoFeB (0.5t<2 nm)/MgO (2.5 nm)/CoFeB (3 nm) have been fabricated. The bias voltage dependence of tunneling ...
Tunnel magnetoresistance of disordered low-moment Co2MnSi Heusler alloy films
(American Institute of Physics, 2005)
Thin films of Co(1?x?y)MnxSiy (x = 0.18?0.26 and y = 0.23?0.29) were deposited from elemental targets onto thermal-oxidized Si substrates at room temperature using dc magnetron cosputtering. The as-deposited films appear ...
Permanent magnet variable flux sources.
(IEEE, 1994)
Rotatable transversely-magnetized permanent magnet rods can be used to generate variable, uniform magnetic fields or field gradients. A four-rod device for use at the specimen stage of an optical microscope is described ...
Magnetite Schottky barriers on GaAs substrates
(American Institute of Physics, 2005)
Thin films of HfO2 produced by pulsed-laser deposition on sapphire, yttria-stabilized zirconia, or silicon substrates show ferromagnetic magnetization curves with little hysteresis and extrapolated Curie temperatures far ...
Torque in nested Halbach cylinders
