Insulating transition in the flux-flow resistivity of a high temperature superconductor
Benjamin Morgan, D. M. Broun, Ruixing Liang +3
Measurements of the DC resistivity of under-doped cuprate superconductors have revealed a metal--insulator transition at low temperatures when superconductivity is suppressed by a…
Apparatus for high resolution microwave spectroscopy in strong magnetic fields
W. A. Huttema, B. Morgan, P. J. Turner +5
We have developed a low temperature, high-resolution microwave surface impedance probe that is able to operate in high static magnetic fields. Surface impedance is measured by cavi…
Superfluid Density in a Highly Underdoped YBCO Superconductor
D. M. Broun, W. A. Huttema, P. J. Turner +5
The superfluid density rho_s(T) = 1/lambda^2(T) has been measured at 2.64 GHz in highly underdoped YBCO, at 37 dopings with T_c between 3 K and 17 K. Within limits set by the trans…
