Tunnelling magnetoresistance of the half-metallic compensated ferrimagnet Mn<inf>2</inf>Ru<inf>x</inf>Ga
(2016)
Tunnel magnetoresistance ratios of up to 40% ar
e measured between 10 K and 300 K when the highly
spin-polarized compensated ferrimagnet, Mn

Nanoscale dissipation and magnetoresistive 1/f noise in spin valves
(2011)
Spatial correlations of 1/f noise in yoke-shaped, giant magnetoresistance spin valve sensors are reported. An upper bound of 135 nm, corresponding to a magnetic volume of <10(5) nm(3), is determined for the lateral size ...
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 ...
Spin-flip noise due to nonequilibrium spin accumulation
(2016)
When current flows through a magnetic tunnel junction (MTJ), there is spin accumulation at the electrode-barrier interfaces if the magnetic moments of the two ferromagnetic electrodes are not aligned. Here we report that ...
Conductance enhancement due to interface magnons in electron-beam evaporated MgO magnetic tunnel junctions with CoFeB free layer deposited at different pressure
(2014)
Electron-beam evaporated MgO-based magnetic tunnel junctions have been fabricated with the
CoFeB free layer deposited at Ar pressure from 1 to 4 mTorr, and their tunneling process has been
studied as a function of ...
Enhanced energy product in Y-Co-Fe magnets intermediate between Nd-Fe-B and ferrite
(2015)
The hysteresis of ball-milled Fe-doped YCo5 powder has been optimized by controlling the temperature and time for rapid annealing under vacuum and argon. The crystallite size is only 25 nm; yet, it has been possible to ...
Electrodeposition of coercive L10 FePd and FePt magnets
(Elsevier, 2010)
We report the preparation, characterization of structure and magnetic properties of electrodeposited L10 FePt films
with high coercivity. Equiatomic as-deposited films are nanocrystalline, soft and magnetically isotropic. ...
Influence of growth conditions on magnetite nanoparticles electro-crystallized in the presence of organic molecules.
(2013)
Magnetite nanoparticles were synthesi
zed by electrocryst
allization in the
presence of thiourea or sodium butanoate as
an organic stabiliz
er. The synthesis was
performed in a thermostatic electrochemical
cell ...
Dependence of charge carrier injection on the interface energy barrier in short-channel polymeric field effect transistors
(2012)
The influence of contact materials on the electrical characteristics of field-effect transistors made
from poly(3-hexylthiophene) with short-channel lengths of 80nm is investigated. The thermally
activated output current ...
Magnetic Properties of Exchange-Biased [Co/Pt](n) Multilayer With Perpendicular Magnetic Anisotropy
(2010)
Perpendicular exchange-biased [Co/Pt](3)/Co(t(Co))/IrMn and IrMn/Co(t(Co))/Pt/[Co/Pt](3) multilayers have been fabricated, changing the thickness (t(Co)) of the cobalt that is next to the IrMn layer. The crystal structure, ...
