Direct measurement of the anisotropy of the resistivity in the a-b plane of twin-free, single-crystal, superconducting YBa2Cu3O7-
Friedmann, T. A.; Rabin, M. W.; Giapintzakis, John; Rice, J. P.; Ginsberg, D. M. (1990)We have measured the resistivity tensor in one nearly twin-free crystal and one twin-free crystal of YBa2Cu3O7-. The first crystal was grown with a large twin-free region. We removed the twins in the second crystal by ...

Hall effect above Tc in untwinned single-crystal YBa2Cu3O7-x: Normal-state behavior and superconducting fluctuations
Rice, J. P.; Giapintzakis, John; Ginsberg, D. M.; Mochel, J. M. (1991)We present a measurement of the Hall coefficient RH for an untwinned single crystal of YBa2Cu3O7-x. The crystal was produced by a method that does not involve thermomechanical detwinning, and has a resistivity along the ...

Hall effect in an untwinned single crystal of YBa2Cu3O7-x
Rice, J. P.; Giapintzakis, John; Ginsberg, D. M.; Mochel, J. M. (1991)The Hall coefficient RH for untwinned single-crystal YBa2Cu3O7-x has been measured for the first time. The crystal was produced by a technique not requiring the application of stress. The measurements are made above the ...

In-plane paraconductivity in a single crystal of superconducting YBa2Cu3O7-x
Friedmann, T. A.; Rice, J. P.; Giapintzakis, John; Ginsberg, D. M. (1989)Resistivity measurements have been made in the a-b plane on a single-crystal sample of superconducting YBa2Cu3O7-x. The resistivity versus temperature curve shows a highly linear region between 150 and 240 K, with an upward ...

Production and identification of flux-pinning defects by electron irradiation in YBa2Cu3O7-x single crystals
Giapintzakis, John; Lee, W. C.; Rice, J. P.; Ginsberg, D. M.; Robertson, I. M.; Wheeler, R.; Kirk, M. A.; Ruault, M.-O. (1992)An enhancement in Jc of YBa2Cu3O7-x single crystals in a magnetic field is observed after irradiation with 1-MeV electrons. Typically, a factor-of-2 increase in Jc is deduced from magnetic hysteresis loops at 10 K and 1 T ...
