Magnetic transitions in strong coupling expansions for nearly degenerate states
Raymond Fresard, Christian Hackenberger, Thilo Kopp
We consider a strong coupling expansion for a two-band Hubbard model on two sites with nearly degenerate states. A comparative analysis is performed for different schemes of pertur…
The antiferromagnetic insulator Ca3FeRhO6: characterization and electronic structure calculations
V. Eyert, U. Schwingenschloegl, R. Fresard +5
We investigate the antiferromagnetic insulating nature of Ca3FeRhO6 both experimentally and theoretically. Susceptibility measurements reveal a Neel temperature T_N = 20 K, and a m…
Magnetic ordering in trigonal chain compounds
V. Eyert, U. Schwingenschloegl, C. Hackenberger +3
We present electronic structure calculations for the one-dimensional magnetic chain compounds Ca_3CoRhO_6 and Ca_3FeRhO_6. The calculations are based on density functional theory a…
