Abstract(#br)We studied theoretically the crystal field and Zeeman split electronic levels of trivalent rare earths that are distributed over trigonal prismatic sites of the layered R x / 3 CoO 2 system (closely related to sodium cobaltate Na x CoO 2 ). The calculations were done in the whole basis ...
