| Summary: | 碩士 === 國立成功大學 === 物理學系碩博士班 === 93 === We have measured the X-ray diffraction patterns, resistivity , magnetoresistance of (Cu9Zr4)100-xTix (x = 7.5、10、12.5 and 15) bulk amorphous . From the X-ray diffraction patterns, we can see that all these samples have good amorphous phase. The temperature coefficient of resistivity (TCR) for these bulk amorphous is all negative. The observed resistivity and magnetoresistance can be interpreted in terms of the quantum interference effect (QIE). From the low-temperature resistivity data, the electron-electron interaction is the main contribution for the observed resistivity below 10K.
