Thermodynamics of a Fermi liquid in a magnetic field
Joseph Betouras, Dmitry Efremov, Andrey Chubukov
We present calculations of the non-analytic terms in the spin susceptibility chi_s(T) and the specific heat C(T) to systems in a magnetic field. Without a field, chi_s(T) and C(T)/…

Orbital ordering in manganites in the band approach
D. V. Efremov, D. I. Khomskii
We consider the orbital ordering in LaMnO3 and similar systems, proceeding from the band picture. We show that for the realistic magnetic structure of A-type there exists a complet…
