Epitaxial growth of FeSeTe thin films on CaF substrates with high critical current density
I. Tsukada, M. Hanawa, T. Akiike +8
In-situ epitaxial growth of FeSeTe thin films is demonstrated on a non-oxide substrate CaF. Structural analysis reveals that compressive stress is moderately ad…
Superconductivity of FeSeTe Thin Films Grown by Pulsed Laser Deposition
Yoshinori Imai, Ryo Tanaka, Takanori Akiike +3
FeSeTe thin films with PbO-type structure are successfully grown on MgO(100) and LaSrAlO(001) substrates from FeSeTe polycrystalline targets by…
Comparative study of macroscopic quantum tunneling in Bi_2Sr_2CaCu_2O_y intrinsic Josephson junctions with different device structures
K. Ota, K. Hamada, R. Takemura +6
We investigated macroscopic quantum tunneling (MQT) of BiSrCaCuO intrinsic Josephson junctions (IJJs) with two device structures. One is a nanometer-thick small mes…
Broadband method for precise microwave spectroscopy of superconducting thin films near the critical temperature
H. Kitano, T. Ohashi, A. Maeda
We present a high-resolution microwave spectrometer to measure the frequency-dependent complex conductivity of a superconducting thin film near the critical temperature. The instru…
Critical charge dynamics of superconducting LSCO thin films probed by complex microwave spectroscopy: Anomalous changes of the universality class by hole doping
T. Ohashi, H. Kitano, I. Tsukada +1
We study the critical charge dynamics of the superconducting to the normal-state transition for LSCO thin films with a wide range of the Sr concentration, by measuring the frequenc…
Critical microwave-conductivity fluctuations across the phase diagram of superconducting LaSrCuO thin films
Haruhisa Kitano, Takeyoshi Ohashi, Atsutaka Maeda +1
We report a systematic study of the dynamic microwave conductivity near for LaSrCuO (LSCO) thin films with =0.07 to 0.16. The strong frequency dependence o…
