Effect of Impurities on the Superheating field of Type II superconductors
Impurities the Superheating field Type II superconductors
2012/2/27
We consider the effect of nonmagnetic and magnetic impurities on the superheating field $H_s$ in a type-II superconductor. We solved the Eilenberger equations, which take into account the nonlinear pa...
We used a quantum Monte Carlo method to study the magnetic impurity adatoms on graphene. We found that by tuning the chemical potential we could switch the values of the impurity local magnet moment b...
Amplifying single impurities immersed in a gas of ultra cold atoms
ultra cold atoms impurities
2011/9/15
We present a method for amplifying a single or scattered impurities immersed in a background gas of ultra cold atoms so that they can be optically imaged and spatially resolved. Our approach relies on...

We study striped morphologies induced by magnetic impurities in d-wave superconductors
(DSCs) near optimal doping by self-consistently solving the Bogoliubov-de Gennes equations based on the t −...
Scattering of band carriers by neutral and charged impurities
Scattering of band carriers by neutral charged impurities
2010/11/24
Mobility of band carriers scattered on donors, partially ionized, partially neutral, is considered in general and calculated for crystals of AIII-BV group. As neutral impurity we have constructed the ...
Local electronic structure of Fe$^{2+}$ impurities in MgO thin films: Temperature-dependent soft x-ray absorption spectroscopy study
Local electronic structure of Fe$^{2+}$ impurities Temperature-dependent soft x-ray absorption spectroscopy study
2010/11/18
We report on the local electronic structure of Fe impurities in MgO thin films. Using soft x-ray absorption spectroscopy (XAS) we verified that the Fe impurities are all in the 2+ valence state.The fi...
Interaction anisotropy and random impurities effects on the critical behaviour of ferromagnets
Interaction anisotropy random impurities effects critical behaviour of ferromagnets
2010/11/23
The theory of phase transitions is based on the consideration of "idealized" models, such as the Ising model: a system of magnetic moments living on a cubic lattice and having only two accessible stat...

The first-principles molecular cluster discrete variational method (DV) is used to investigate the electronic structure and local magnetic properties of Cr impurities in bcc iron and Fe/Cr interfaces....
Contribution of the Spin Current to the Damping of the Magnetic Moment Precession of Fe Impurities in Pd
Spin waves Giant magnetic moment Spin current
2010/9/25
We investigate the spin dynamics of a magnetic adatom on a non-magnetic surface with strong Stoner enhancement. We find a strong damping of the adatom’s magnetization precession and a large shift of t...
Polaron Dynamics with Impurities in Conjugated Polymers
Polaron Dynamics Impurities Conjugated Polymers
2010/10/15
We study the charge transport by polarons in conjugated polymers in the presence of impurities. The effects on the polaron motion due to the symmetry of the chain is considered. The polaron dynamics i...
