Pressure effect on quasi-one-dimensional charge transport in PrBa2Cu4O8: Magnetotransport study

摘要

The electrical resistivity and the magnetoresistance of PrBa2Cu4O8 have been measured under hydrostatic pressure up to 1.0 GPa. It was found that magnetoresistance is sensitive to the applied pressure below 100 K where the resistivity shows metallic behavior. This suggests that the interchain hopping energy is increased by pressure, which makes the low-temperature electronic state more two dimensional. [S0163-1829(99)01505-2]. [References: 12]
