Abstract
The electronic structure around the ideal 3d transition metal impurities at substitutional site of germanium is calculated self-consistently within the local density formalism. Chemical trend of 3d impuritiy levels caused by the strong p-d hybridization, is revealed in the case of non-magnetic state. The magnetic state of the iron impurity is also presented and the local magnetic moment experienced by iron impurity is calculated to be 3.72μ B.
