Since the discovery of high Te superconductors the magnetism of various copper-oxides has attracted much interest.Especially the magnetism of strong spin correlation systems in various CuO4 networks is of great interest because it is wellknown that the superconductivity is occuring in the CuO2 plane of the high TT superconductors. Here we will show some ofour works done on copper-oxides by submillimeter wave ESR. Our submillimeter wave ESR can provide the frequencyregion of 90-3100 GHz and the pulse magnetic field up to 30T. The details of our experimental methods can be found in ref.1 and 2.
