摘要

Low temperature M枚ssbauer experiments were performed in Fe-doped and in C-deficiency MgCNi<sub>3sub>. No magnetic moment was found for Fe in MgC(Ni<sub>0.99sub>Fe<sub>0.01sub>)<sub>3sub> sample and no magnetic hf field was observed at any temperature for all the samples. These results shown no evidence of magnetic fluctuation or magnetic ordering influencing the depress of superconductivity in hole-doped MgCNi<sub>3sub>.
