Magnetism in thin films of CaB6 and SrB6
(American Physical Society, 2004)
Thin films of disordered hexaborides CaB6 and SrB6 deposited by pulsed-laser deposition on MgO
(100) or Al2O3 (001) substrates are ferromagnetic. A typical room-temperature moment per unit area
of substrate is 350 mB ...
Nickel sulfide - an itinerant electron antiferromagnet.
(American Physical Society, 1974)
Antiferromagnetic nickel sulphide has a small temperature-independent magnetic susceptibility. The ordered moment per nickel atom, measured with neutrons, decreases from 1.45?B to 1.00?B at 4.2 K with a decrease of 0.6% ...
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 ...
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 ...
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 ...
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 ...

Thick film permanent magnets by membrane electrodeposition
(American Institute of Physics, 2005)
Thick films of nearly equiatomic Co?Pt produced by electrodeposition into nanoporous membranes exhibit an isotropic magnetic phase with square hysteresis loops (Mr/Ms = 0.95) and coercivity of up to 1.3 T. The initial ...
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 ...
