Modeling nonlinearity and hysteresis due to critical-state flux penetration in hard superconductors
T. Dasgupta, Durga P. Choudhury, S. Sridhar
The nonlinear surface impedance of a thin superconducting strip carrying a microwave current has been calculated numerically from first principles based upon flux penetration due t…
Harmonic generation from YBCO microwave resonators
Durga P. Choudhury, John S. Derov, S. Sridhar
Measurement of harmonic power on a suspended stripline microwave resonator patterned out of thin film YBa_2Cu_3O_7 (YBCO) has been carried out as a function of temperature and micr…
Magneto-electrodynamics at high frequencies in the antiferromagnetic and superconducting states of DyNi_2B_2C
Durga P. Choudhury, H. Srikanth, S. Sridhar +1
We report the observation of novel behaviour in the radio frequency (rf) and microwave response of DyNi_2B_2C over a wide range of temperature (T) and magnetic field (H) in the ant…
Nonlinear Response of HTSC Thin Film Microwave Resonators in an Applied DC Magnetic Field
Durga P. Choudhury, Balam A. Willemsen, John S. Derov +1
The non-linear microwave surface impedance of patterned YBCO thin films, was measured using a suspended line resonator in the presence of a perpendicular DC magnetic field of magni…
Comments on "Vortex Glass and Lattice Melting Transitions in a YNi_2B_2C Single Crystal"
S. Sridhar, S. Oxx, B. A. Willemsen +2
Recently, Mun et.al. (Phys. Rev. Lett., 76, 2790 (1996)) have published their results on single crystal YNi_2B_2C, claiming that their experimental observations can be explained in…
Vortex Response and Critical Fields observed via rf penetration depth measurements on the superconductor YNi_2B_2C
S. Oxx, D. P. Choudhury, Balam A. Willemsen +4
Measurements of the rf penetration depth λ(T,H,θ) are used to study the superconducting order parameter, vortex dynamics in the mixed state and delineate critical fields in the bor…
