Abstract

A novel class of superconducting oxides commonly form the CuO2 lamellars. Neutron scattering experiments revealed the existence of the antiferromagnetic long range order in the undoped progenitors. The local crystal symmetry around Cu2+ governs the antiferromagnetic structure and related magnetic phase transitions. The two dimensional antiferromagnetic spin correlations persisting even in the superconducting states is discussed in our view that the magnetism has-an intimate relation to the appearance of the high temperature superconductivity.
