内容記述 |
The pressure effect on the Hall coefficient RH has been studied in Ca and oxygen co-doped Y12xCaxBa2Cu3Oy systems. RH is not altered by pressure in samples without a Cu-O chain, whereas samples with an oxygen-deficient chain are altered in response to pressure, thus demonstrating the contribution of the oxygen reordering effect. However, even in samples with full chain ordering, RH changes at a rate of 28.3%/GPa. This suggests the contribution of internal strain due to the presence of a Cu-O chain structure. We independently estimated the effect of two factors, oxygen reordering and internal strain, on the pressure effect on RH . The oxygen-content dependence of the pressure effect on RH can be explained by competition between oxygen reordering and internal strain. |
