Ginzburg-Landau theory and effects of pressure on a two-band superconductor : application to MgB2
J. J. Betouras, V. A. Ivanov, F. M. Peeters
We present a model of pressure effects of a two-band superconductor based on a Ginzburg-Landau free energy with two order parameters. The parameters of the theory are pressure as w…
Superconductivity in mesoscopic high- superconducting particles
V. A. Ivanov, V. R. Misko, V. M. Fomin +1
Based on the Hubbard model in the framework of non-phonon kinematical mechanism and taking into account the discreetness of an electronic energy spectrum, the superconducting criti…
On the nature of ferromagnetism in diluted magnetic semiconductors: GaAs:Mn, GaP:Mn
V. A. Ivanov, P. M. Krstajic, F. M. Peeters +2
A microscopic Hamiltonian for interacting manganese impurities in diluted magnetic semiconductors (DMS) is derived. It is shown that in p -type III-V DMS the indirect exchange betw…
Pressure Effects and Large Polarons in Layered MgB_2 Superconductor
V. A. Ivanov, M. A. Smondyrev, J. T. Devreese
We consider the dependence of the MgB_2 superconducting critical temperature on the pressure. Our model exploits the influence of the large polarons on the band structure of the la…
MgB2: superconductivity and pressure effects
V. A. Ivanov, J. J. Betouras, F. M. Peeters
We present a Ginzburg-Landau theory for a two-band superconductor with emphasis on MgB. Experiments are proposed which lead to identification of the possible scenarios: wheth…
Strongly interacting -electrons and MgB superconductivity
V. A. Ivanov, M. van den Broek, F. M. Peeters
MgB is classified as a system with strongly interacting -electrons and non-correlated -electrons of boron ions. The kinematic and Coulomb interaction V…
