It has been suggested that the two EPR signals (g=1.982 and g=4.1) originate from separate PS II electron donors that are in a redox equilibrium with each other in the S2 state and that the g=4.1 signal arises from monomeric MnIV [3]. However, a tetramanganese cluster consisting of a...

The preliminary results of EPR experiments on superconducting Mn-YBaCuO composites are reported. The measurements were done in X band in the temperature range 4–300 K. Three distinct EPR components were observed possessing different g-factors and a rather different temperature behavior. For similar ...
