Abstract
Two types of spin-polarized clusters confining the motion of oxygen ho les in layered cuprates ace discussed. The first one containing five c opper sites has a total spin S = 2, whereas most essential elements of the second one are four coppers and it is characterised by S = 3/2. A nisotropic exchange coupling splits the magnetic ground state into a s equence of state, which in a natural way provide e.g. an explanation o f EPR data for La2CuO4+delta compounds.
