Charge and spin fluctuations Cu2+ (S=1/2) ↔ Cu3+ (S=1) in HTSCs. New Model of narrow impurity bands
Description
The energy band of oxide superconductors is theoretically investigated when charge and spin fluctuations of Cu2+(S=1/2)-O-(S=0)↔Cu3+(S=1)-O2-(S=1/2) take place. It is shown that two narrow bands arise near Fermi level under hole doping. The dynamic admixture of 3z2-r2 state to the x2-y2 state is equal to approximately 10%. (orig.)
