Higher harmonic resistance oscillations in micro-bridge superconducting Nb ring
Masashi Tokuda, Ryoya Nakamura, Masaki Maeda +1
We studied resistance oscillations in two types of superconducting mesoscopic Nb rings. In a simple superconducting ring device, a resistance oscillation with a period of the quant…
Thickness-induced crossover from strong to weak collective pinning in exfoliated FeTeSe thin films at 1 T
Ryoya Nakamura, Masashi Tokuda, Mori Watanabe +3
We studied flux pinning in exfoliated FeTeSe thin-film devices with a thickness from 30 to 150 nm by measuring the critical current density . In…
Two Phase Collective Modes in Josephson Vortex Lattice in Intrinsic Josephson Junction BiSrCaCuO
I. Kakeya, T. Wada, R. Nakamura +1
Josephson plasma excitations in the high superconductor BiSrCaCuO have been investigated in a wide microwave frequency region (9.8 -- 75 GHz), in particul…
Josephson Plasma Resonance in Solid and Glass Phases of BiSrCaCuO
I. Kakeya, R. Nakamura, T. Wada +1
Vortex matter phases and phase transitions are investigated by means of Josephson plasma resonance in under-doped BiSrCaCuO single crystals in a microwave frequ…
Josephson Plasma Mode in Fields Parallel to Layers of Bi_2Sr_2CaCu_2O_{8+δ}
I. Kakeya, T. Wada, R. Nakamura +1
Josephson plasma resonance measurements under magnetic fields parallel to the CuO_2 layers as functions of magnetic field, temperature, and microwave frequency have been performed…
