A Manganese Ions Ground State in MnxSi1–x: Negative- U Properties Centre?
Abstract: In the paper, the properties of magnetic diluted and strong correlated systems of MnxSi1–x systems are discussed. The double defects including manganese ion and silicon vacancy are the frame work of the our model introduced for the description of these systems properties. The role of the Jahn-Teller distortions of different symmetry types in MnSi system magnetic-properties formation is discussed. It has been established that the manganese related defect is the center with negative-U properties and Jahn-Teller’s full symmetric vibration mode initiates change of a crystal-field value from intermediate to strong.
