Description

Neutron scattering probed novel two dimensional antiferromagnetic spin correlations in pure La2CuO4 which is the mother compound of high temperature superconductors of doped La2-xMxCuo4. Cu2+ moments are ordered instantaneously over very large areas in the CuO2 plane but there is no measurable time averaged staggered moment. Since the dynamical behavior observed is similar to that in the quantum antiferromagnetic chain, the authors conclude that spin fluctuations observed at finite temperatures are quantum spin liquid state, like that in quantum antiferromagnetic chain at T = O
