| 概要 | Underdoped YBa2Cu3O7-δ single crystals exhibit a large, positive c-axis magnetoresistance that is strikingly linear over a wide magnetic field range up to 60 T. This linear magnetoresistance is observed at temperatures near or below Tc, once sufficient magnetic field has been applied to suppress superconductivity. The measurements are done in the longitudinal geometry, with current and magnetic field both along the c-axis (I∥B∥c). The linear magnetoresistance can be large, giving as much as a 35% increase in resistance between 30 T and 60 T. It also exhibits very strong temperature dependence, increasing by as much as an order of magnitude as the temperature is reduced from 100 K to 10 K. © 2000 Elsevier Science B.V.
