Anomalous magnetoresistance behavior of superconducting Nd{sub 2-x}Ce{sub x}CuO{sub 4-y} single crystal
Abstract
Magnetoresistance measurements on a superconducting Nd{sub 2- x}Ce{sub x}CuO{sub 4-y} single crystal with {Tc} {approx} 7 K were made with magnetic fields H applied parallel (H {parallel} c) and perpendicular (H {perpendicular} c) to the tetragonal c-axis. For H {parallel} c, the resistive superconductive transition curves exhibit a double transition at low temperatures and high magnetic fields. This double resistive transition has a maximum near T {approx} 1.1 K, followed by an extremely sharp transition into the superconducting state. For applied fields of 1kOe, the resistivity first goes to zero, increases again to a finite value and then goes through a second transition. In this region, the resistivity exhibits non-ohmic behavior for low current densities and ohmic behavior for larger measuring currents. The resistivity for H {perpendicular} c does not exhibit any anomalous behavior or a maximum for 0 {le} H {le} 60 kOe and 4 {le} T {le} 7 K.
