Effect of anisotropic spin-spin coupling of cooper and oxygen holes in spin-polarized clusters

Eremin M.; Sigmund E. (1994)

Two types of spin-polarized clusters confining the motion of oxygen holes in layered cuprates are discussed. The first one containing five copper sites has a total spin S = 2, whereas most essential elements of the second ...
On the importance of anisotropic exchange coupling on to the structure of spin-polarized clusters in layered cuprates

Eremin M.; Sigmund E. (1994)

The low energy spectrum of spin-polarized clusters in layered cuprates is examined. Two types of clusters confining the motion of oxygen holes are discussed. The ground state of the pentanuclear copper cluster has a total ...

The spin susceptibility of singlet correlated oxygen band in La2-xSrxCuO4

Eremin M.; Sigmund E.; Solovjanov S.; Varlamov S. (1996)

We have shown that the unconventional temperature dependence of the static susceptibility χ(T) of the perovskite high-Tc superconductors above the superconducting transition temperature Tc can be explained in terms of two ...
