Abstract

The ESR measurements of Co-based diluted magnetic semiconductors were carried out in the far-infrared range using pulsed high magnetic fields up to 30 T. The g-factor of Cd0.9gCo0.02Te was determined to be g*=2.294±0.003, and thezero-field splitting parameter 2D of Cdo.99Coo.oiSe was directly determined to be 0.9±0.1 cm-1. These results were explained by the energy-level diagrams of a single Co2+ ion in a crystal field.
