Improved electronic measurement of the Boltzmann constant by Johnson noise Thermometry
Jifeng Qu, Samuel P Benz, Alessio Pollarolo +4
The unit of thermodynamic temperature, the kelvin, will be redefined in 2018 by fixing the value of the Boltzmann constant, k. The present CODATA recommended value of k is determin…
Spin-transfer torque switching in nanopillar superconducting-magnetic hybrid Josephson junctions
Burm Baek, William H. Rippard, Matthew R. Pufall +4
The combination of superconducting and magnetic materials to create novel superconducting devices has been motivated by the discovery of Josephson critical current (Ics) oscillatio…
Sensitivity of Double-Sided Split Ring Resonator Arrays to Fabrication Tolerances
Frank Trang, Edward F. Kuester, Horst Rogalla +1
We present a study of the effects of fabrication tolerances on the performance of a planar array of double-sided split-ring resonators, printed on two sides of a dielectric substra…
An Electronic Measurement of the Boltzmann Constant
Samuel P. Benz, Alessio Pollarolo, Jifeng Qu +5
The Boltzmann constant was measured by comparing the Johnson noise of a resistor at the triple point of water with a quantum-based voltage reference signal generated with a superco…
Vortex Trapping in Hybrid Magnetometers
K. H. Kuit, J. R. Kirtley, H. Rogalla +1
Hybrid magnetometers based on a normal conducting sensor and a superconducting flux concentrator have been investigated. When this sensor is operated in an unshielded environment f…
Vortex trapping and expulsion in thin-film type-II superconducting strips
K. H. Kuit, J. R. Kirtley, J. R. Clem +2
Vortex trapping is investigated in thin-film strips of superconducting material. We present a model for the critical field above which vortex trapping occurs in these strips. This…
