Giant frequency dependence of dynamic freezing in nanocrystalline ferromagnetic LaCo0.5Mn0.5O3
R. Mahendiran, Y. Briead, M. Hervieu +2
This paper is withdrawn now and soon will be replaced by a complete study on LaCo0.5-MgxMn0.5O3.
Patterned nanostructure in AgCo/Pt/MgO(001) thin film
Zhi-Rong Liu, Huajian Gao, L. Q. Chen +1
The formation of patterned nanostructure in AgCo/Pt/MgO(001) thin film is simulated by a technique of combining molecular dynamics and phase-field theory. The dislocation (strain)…
Ultra-sharp magnetization steps in perovskite manganites
R. Mahendiran, A. Maignan, S. Hebert +5
We report a detailed study of step-like metamagnetic transitions in the magnetization and resistivity of polycrystalline Pr0.5Ca0.5Mn0.95Co0.05O3. The steps have a sudden onset bel…
Predicted Infrared and Raman Spectra for Neutral Ti_8C_12 Isomers
Tunna Baruah, Mark R. Pederson, M. L. Lyn +1
Using a density-functional based algorithm, the full IR and Raman spectra are calculated for the neutral Ti_8C_12 cluster assuming geometries of Th, Td, D2d and C3v symmetry. The T…
Highly enhanced Curie temperatures in low temperature annealed (Ga,Mn)As epilayers
K. C. Ku, S. J. Potashnik, R. F. Wang +9
We report Curie temperatures up to 150 K in annealed Ga1-xMnxAs epilayers grown with a relatively low As:Ga beam equivalent pressure ratio. A variety of measurements (magnetization…
Neutron Diffraction Study of Field Cooling Effects on Relaxor Ferroelectrics Pb[(Zn_{1/3} Nb_{2/3})_{0.92} Ti_{0.08}] O_{3}
Kenji Ohwada, Kazuma Hirota, Paul W. Rehrig +2
High-temperature (T) and high-electric-field (E) effects on Pb[(Zn_{1/3} Nb_{2/3})_{0.92} Ti_{0.08}]O_3 (PZN-8%PT) were studied comprehensively by neutron diffraction in the ranges…
Spin-polarized Tunneling in Hybrid Metal-Semiconductor Magnetic Tunnel Junctions
S. H. Chun, S. J. Potashnik, K. C. Ku +2
We demonstrate efficient spin-polarized tunneling between a ferromagnetic metal and a ferromagnetic semiconductor with highly mismatched conductivities. This is indicated by a larg…
Spectroscopic determination of hole density in the ferromagnetic semiconductor GaMnAs
M. J. Seong, S. H. Chun, Hyeonsik M. Cheong +2
The measurement of the hole density in the ferromagnetic semiconductor GaMnAs is notoriously difficult using standard transport techniques due to the dominance of the…
Dirty Spin Ice: The Effect of Dilution on Spin Freezing in Dy2Ti2O7
J. Snyder, J. S. Slusky, R. J. Cava +1
We have studied spin freezing in the diluted spin ice compound Dy2-xYxTi2O7 where the non-magnetic Y ions replace the magnetic Dy ions on the frustrated pyrochlore lattice. Magneti…
In situ epitaxial MgB2 thin films for superconducting electronics
X. H. Zeng, A. V. Pogrebnyakov, A. Kotcharov +11
A thin film technology compatible with multilayer device fabrication is critical for exploring the potential of the 39-K superconductor magnesium diboride for superconducting elect…
Above-Room-Temperature Ferromagnetism in GaSb/Mn Digital Alloys
X. Chen, M. Na, M. Cheon +9
Digital alloys of GaSb/Mn have been fabricated by molecular beam epitaxy. Transmission electron micrographs showed good crystal quality with individual Mn-containing layers well re…
Simple Model of Capillary Condensation in porous media
S. M. Gatica, M. M. Calbi, M. W. Cole
We employ a simple model to describe the phase behavior of 4He and Ar in a hypothetical porous material consisting of a regular array of infinitely long, solid, parallel cylinders.…
Electric-field induced phase transitions in rhombohedral PZN-xPT
B. Noheda, Z. Zhong, D. E. Cox +3
High-energy x-ray diffraction experiments peformed on rhombohedral (1-x)Pb(Zn1/3Nb2/3)O3-xPbTiO3(PZN-xPT) crystals with x= 4.5 and 8% show that an electric field applied along the…
