The Effect of Chemisorption on the Magnetic Behavior of Metastable Layers of fcc Co(001) and Fe(001) (Abstract)

Mankey, Gary (American Institute of Physics, 1990)

We have investigated the effect of chemisorption on the magnetic properties of metastable layers of fcc Co(001) and fcc Fe(001) epitaxed to Cu(001) substrates. The Curie temperature has been observed to fall rapidly with ...
Effect of Interface Roughness on the Exchange Bias for NiFe/FeMn

Mankey, Gary (AIP Publishing, 2000-04-28)

The effect of interface roughness on exchange bias for NiFe/FeMn bilayers is investigated for polycrystalline films and epitaxial films. Three different systems were investigated: polycrystalline Ta (10 nm)/Ni_80Fe_20 (10 ...
The Effect of Microstructure on the Magnetic Behavior of Epitaxial Cobalt Layers

Mankey, Gary (American Vacuum Society, )

We have studied the magnetic behavior of thin cobalt films epitaxed on a Cu (001) substrate as a function of their growth temperature. At 150 K, the film texture is rough and the surface coverage is incomplete for film ...
Effect of Substrate Symmetry on the Preferred Magnetization Orientation of Ni Films on Cu

Mankey, Gary (1998-06-04)

For ultrathin Ni films grown on Cu(100) and Cu(110), the easy axis of magnetization starts out in the plane of the films. Above a critical thickness, the preferred magnetization orientation changes to perpendicular to the ...
Effective Theoretical Approach of Gauge-Higgs Unification Model and Its Phenomenological Applications

Okada, Nobuchika (SISSA, 2006-02-28)

We derive the low energy effective theory of Gauge-Higgs unification (GHU) models in the usual four dimensional framework. We find that the theories are described by only the zero-modes with a particular renormalization ...
Effective Theory of Brane World with Small Tension

Okada, Nobuchika (2000-04-21)

The five dimensional theory compactified on S¹ with two “branes” (two domain walls) embedded in it is constructed, based on the field-theoretic mechanism to generate the “brane.” Some light states localized in the “brane” ...
The Effects of Curvature and Expansion on Helium Detonations on White Dwarf Surfaces

Moore, Kevin; Townsley, Dean M.; Bildsten, Lars (2013-10-20)
Effects of Unparticles on Top Spin Correlation at the Large Hadron Collider

Okada, Nobuchika (American Physical Society, 2009-04-21)

We study effects of the scale-invariant hidden sector, the unparticle, proposed by Georgi, on top spin correlation at the Large Hadron Collider. Assuming no flavor-changing interaction between the unparticles and the ...
Electroweak Vacuum Stability in Classically Conformal B−L Extension of the Standard Model

Okada, Nobuchika (2017-02-23)

We consider the minimal U(1)_(B-L) extension of the standard model (SM) with the classically conformal invariance, where an anomaly-free U(1)_(B-L) gauge symmetry is introduced along with three generations of right-handed ...
Elemental Abundancies in the X-ray Gas of Early-type Galaxies with XMM-Newton and Chandra Observations

Ji, Jun; Irwin, Jimmy A.; Athey, Alex; Bregman, Joel N.; Lloyd-Davies, Edward J. (2009-05-10)

The source of hot gas in elliptical galaxies is thought to be due to stellar mass loss, with contributions from supernova (SN) events and possibly from infall from a surrounding environment. This picture predicts ...
Emergent Abelian Gauge Fields from Noncommutative Gravity

Allen, Stern (2010-02-18)

We construct exact solutions to noncommutative gravity following the formulation of Chamseddine and show that they are in general accompanied by Abelian gauge fields which are first order in the noncommutative scale. This ...
Enhanced Coercivity of Exchange-bias Fe/MnPd Bilayers

Tang, Y. J.; Roos, B.; Mewes, T.; Demokritov, S. O.; Hillebrands, B.; Wang, Y. J. (1999)

We present detailed studies of the enhanced coercivity of exchange-bias bilayer Fe/MnPd, both experimentally and theoretically. We have demonstrated that the existence of large higher-order anisotropies due to exchange ...
Enhanced Spin Polarization of Conduction Electrons in Ni Explained by Comparison with Cu

Mankey, Gary (2000-06-15)

The spin-split Fermi-level crossings of the conduction band in Ni are mapped out by high-resolution photoemission and compared to the equivalent crossing in Cu. The area of the quasiparticle peak decreases rapidly below ...
Enhanced Spin Pumping Near a Magnetic Ordering Transition

Khodadadi, Behrouz; Mohammadi, Jamileh Beik; Mewes, Claudia; Mewes, Tim; Manno, M.; Leighton, C.; Miller, Casey W. (2017)
Enigmatic Recurrent Pulsational Variability of the Accreting White Dwarf EQ LYN (SDSS J074531.92+453829.6)

Mukadam, Anjum S.; Townsley, D. M.; Szkody, Paula; Gänsicke, B. T.; Southworth, J.; Brockett, T.; Parsons, S.; Hermes, J. J.; Montgomery, M. H.; Winget, D. E.; Harrold, S.; Tovmassian, G.; Zharikov, S.; Drake, A. J.; Henden, A.; Rodriguez-Gil, P.; Sion, E. M.; Zola, S.; Szymanski, T.; Pavlenko, E.; Aungwerojwit, A.; Qian, S.-B. (2013-09)

Photometric observations of the cataclysmic variable EQ Lyn (SDSS J074531.92+453829.6), acquired from 2005 October to 2006 January, revealed high-amplitude variability in the range 1166–1290 s. This accreting white ...
