摘要

Results of magnetization and magnetic susceptibility measurements on undoped and Co-doped FeSi_2.5 single crystals are presented. The temperature dependence of the Magnetic susceptibility of the Co-deped sample in the range of 5-300 K can be Explained by temperature-dependent contributions due to paramagnetic centers and The carriers excited thermally in the extrinsic conductivity region. The values of the Paramagnetic Curie temperature and activation energy of the donor levels were Estimated.
