【 摘 要 】

The electrical resistance of dysprosium metal has been measured as a function of hydrostatic pressure up to 1.2 GPa at temperatures from 300 K to 700 K, and at atmospheric pressure from 80 to 700 K. Our data at atmospheric pressure and at room temperature agree well with literature data. The total pressure coefficient of resistance at 300 K is found to be dlnR/dp = -2.98·10-2GPa-1and to decrease slightly with increasing temperature. The results are discussed in terms of simple free-electron type models.
