Reduction of the field-dependent microwave surface resistance in YBa_2Cu_3O_7 with sub-micrometric BaZrO_3 inclusions as a function of BaZrO_3 concentration
N. Pompeo, R. Rogai, E. Silva +3
In order to study the vortex pinning determined by artificially introduced pinning centers in the small-vortex displacement regime, we measured the microwave surface impedance at 4…
Reliable determination of vortex parameters from measurements of the microwave complex resistivity
N. Pompeo, E. Silva
We discuss and propose a complete data treatment, in close contact to typical microwave experimental data, in order to derive vortex parameters, such as pinning constant and viscou…
Nonlinear c-axis transport in Bi_2Sr_2CaCu_2O_(8+d) from two-barrier tunneling
M. Giura, N. Pompeo, E. Silva
Motivated by the peculiar features observed through intrinsic tunneling spectroscopy of BiSrCaCuO mesas in the normal state, we have extended the normal state t…
Microwave properties of DyBa_2Cu_3O_(7-x) monodomains and related compounds in magnetic fields
N. Pompeo, E. Silva, M. Ausloos +1
We present a microwave characterization of a DyBaCuO single domain, grown by the top-seeded melt-textured technique. We report the (a,b) plane field-induced sur…
Crystal and magnetic structure of (La0.70Ca0.30)(CryMn1-y)O3: a neutron powder diffraction study
L. Capogna, A. Martinelli, M. G. Francesconi +7
The crystal and magnetic structure of (La0.70Ca0.30)(CryMn1-y)O3 for y = 0.70, 0.50 and 0.15 has been investigated using neutron powder diffraction. The three samples crystallize i…
