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…
Ground state of a double-exchange system containing impurities: bounds of ferromagnetism
Eugene Kogan, Mark Auslender, Eran Dgani
We study the boundary between ferromagnetic and non-ferromagnetic ground state of a double-exchange system with quenched disorder for arbitrary relation between Hund exchange coupl…
From the double-exchange Hamiltonian to the model: Classical spins
Eugene Kogan, Mark Auslender
From the double-exchange Hamiltonian with classical localized spins in the limit of large but finit Hund exchange coupling we obtain the model (with classical localized spins…
Comment on low-temperature transport properties of non-stoichiometric La_{0.95-x}Sr_{x}MnO_{3}
E. Rozenberg, M. Auslender
In a recent paper (Michalopolou A., Syskakis E. and Papastaikoudis C., 2001 J. Phys.: Cond. Mat. 13, 11615) the authors reported on the measurements of electrical resistivity and s…
