Measurement of the ab plane anisotropy of microwave surface impedance of untwinned YBa2Cu3O6.95 single crystals.
The temperature dependence of the surface resistance R, and the penetration depth A has been measured in both a and b directions in Yba2cu30695. The overall temperature dependences are similar and show a linear behavior at low T. This argues against the chains playing a direct role in the unconventional behavior of the surface impedance. The residual R, of these twin-free crystals is very small...
متن کاملDetermination of the magnetization scaling exponent for single-crystal La0.8Sr0.2MnO3 by broadband microwave surface impedance measurements
Employing a broadband microwave reflection configuration, we have measured the complex surface impedance, ZS(v ,T), of single-crystal La0.8Sr0.2MnO3, as a function of frequency (0.045–45 GHz) and temperature (250–325 K). Through the dependence of the microwave surface impedance on the magnetic permeability, m̂(v ,T), we have studied the local magnetic behavior of this material, and have extracte...
متن کاملModulated microwave surface impedance of superconducting films
We present details of an experimental method to measure the field modulated surface resistance (dR,/dH) of superconducting films accurately, which enables both field and temperature sweep experiments and is particularly useful for low-field or near T, measurements. The complex surface impedance Z,(H,T) =R,(H,T) + iX,(H, T) can also be simultaneously measured. This technique utilizes specially b...
متن کاملThe superconducting gap of in situ MgB2 thin films by microwave surface impedance measurements
Precision measurements of the microwave surface resistance Rs of in situ MgB2 films directly reveal an exponential behavior of Rs at low temperature indicating a fully-gapped order parameter. The entire temperature dependence of Rs is well described by a Mattis–Bardeen formalism, but with a small gap ratio of D(0)/kTc50.72, corresponding to D(0)51.9 meV. © 2002 American Institute of Physics. @D...
متن کاملSystematics of two-component superconductivity in YBa2Cu3O6.95 from microwave measurements of high-quality single crystals
A systematic set of measurements of the microwave ~10 GHz! surface impedance (Zs5Rs1iXs) of twinned YBa2Cu3O6.95 single crystals ~called YBCO/BZO! grown in BaZrO3 crucibles reveal properties that are not directly seen in similar measurements on other YBCO samples. The complex conductivity s5s12is2 obtained as a function of temperature (T) from the surface impedance data shows two key features :...
