Interplay of Magnetic Exchange Interactions and Ni-S-Ni Bond Angles in Polynuclear Nickel(II) Complexes
Yulia Krupskaya, Alexey Alfonsov, Anupama Parameswaran +7
The ability of bridging thiophenolate groups to transmit magnetic exchange interactions between paramagnetic Ni(II) ions has been examined. For this purpose, dinuclear and trinucle…
On the existence of the excitonic insulator phase in the extended Falicov-Kimball model: an SO(2)-invariant slave-boson approach
B. Zenker, D. Ihle, F. X. Bronold +1
We re-examine the three-dimensional spinless Falicov-Kimball model with dispersive electrons at half-filling, addressing the dispute about the formation of an excitonic condens…
Dynamic spin susceptibility in the t-J model
A. A. Vladimirov, D. Ihle, N. M. Plakida
A relaxation-function theory for the dynamic spin susceptibility in the -- model is presented. By a sum-rule-conserving generalized mean-field approximation (GMFA), the two-s…
Thermodynamics of layered Heisenberg magnets with arbitrary spin
I. Juhász Junger, D. Ihle, J. Richter
We present a spin-rotation-invariant Green-function theory of long- and short-range order in the ferro- and antiferromagnetic Heisenberg model with arbitrary spin quantum number S…
Magnetic order in Graphite: Experimental evidence, intrinsic and extrinsic difficulties
P. Esquinazi, J. Barzola-Quiquia, D. Spemann +5
We discuss recently obtained data using different experimental methods including magnetoresistance measurements that indicate the existence of metal-free high-temperature magnetic…
