Critical behaviour of anisotropic magnets with quenched disorder: replica symmetry breaking studied by operator product expansion
E. Kogan, M. Kaveh
We study critical behaviour of disordered magnets near four dimensions. We consider the system with explicit cubic anisotropy and scalar disorder and that with random direction of…
Replica symmetry breaking for anisotropic magnets with quenched disorder
E. Kogan, M. Kaveh
We study critical behaviour of a magnet with cubic anisotropy and quenched scalar disorder which is taken into account by replica method. We derive to first order in approximat…
Paramagnetic-ferromagnetic transition in a double-exchange model
Eugene Kogan, Mark Auslender
We study paramagnetic - ferromagnetic transition due to exchange interaction between classical localized magnetic moments and conduction electrons. We formulate the Dynamical Mean…
Ferromagnetic transition in a double-exchange model
Eugene Kogan, Mark Auslender, Eran Dgani
We calculate the temperature of a ferromagnetic transition in a double-exchange model with classical core spins for arbitrary relation between Hund exchange coupling and electron b…
Ferromagnetic transition in a double-exchange system containing impurities in the Dynamical Mean Field Approximation
Mark Auslender, Eugene Kogan
We formulate the Dynamical Mean Field Approximation equations for the double-exchange system with quenched disorder for arbitrary relation between Hund exchange coupling and electr…
Ferromagnetic transition in a double-exchange system
Mark Auslender, Eugene Kogan
We study ferromagnetic transition in three-dimensional double-exchange model. The influence of strong spin fluctuations on conduction electrons is described in coherent potential a…
