Precision determination of a fluxoid quantum's magnetic moment in a superconducting micro-ring
Heonhwa Choi, Yun Won Kim, Soon-Gul Lee +3
Using dynamic cantilever magnetometry and experimentally determining the cantilever's vibrational mode shape, we precisely measured the magnetic moment of a lithographically define…
Superconducting Qubits Coupled to Torsional Resonators
Myung-Joong Hwang, Jae-Hyuk Choi, Mahn-Soo Choi
We propose a scheme of strong and tunable coupling between a superconducting phase qubit and nanomechanical torsional resonator. In our scheme the torsional resonator directly modu…
Superconducting properties of well-shaped MgB2 single crystal
Kijoon H. P. Kim, Jae-Hyuk Choi, C. U. Jung +11
We report measurements of the transport and the magnetic properties of high-quality, sub-millimeter-sized MgB2 single crystals with clear hexagonal-plate shapes. The low-field magn…
Three-Dimensional Superconductivity in the Infinite-Layer Compound Sr_{0.9}La_{0.1}CuO_2 in Entire Region below
Mun-Seog Kim, C. U. Jung, J. Y. Kim +2
The infinite-layer compound ACuO (A alkaline-earth ions) is regarded as the most suitable material for exploring the fundamental nature of the CuO plane because it do…
