Path-Dependent Supercooling of the He Superfluid A-B transition
Dmytro Lotnyk, Anna Eyal, Nikolay Zhelev +7
We examine the discontinuous first-order superfluid He A to B transition in the vicinity of the polycritical point (2.232 mK and 21.22 bar). We find path-dependent transitions:…
Superconducting Sweet-Spot in Microcrystalline Graphite Revealed by Point-Contact Spectroscopy
Frank Arnold, Jan Nyeki, John Saunders
In this letter we describe the observation of a magnetic field dependent electronic gap, suggestive of local superconductivity, in the point-contact spectrum of micro-crystalline g…
Micro-coil detection of Nuclear Magnetic Resonance for nanofluidic samples
Aya Shibahara, Andrew Casey, Chris Lusher +4
We have developed a novel dc SQUID system with a micro-coil input circuit to act as a local probe of quantum matter and nanosystems. The planar niobium micro-coil pickup loop is lo…
A nuclear magnetic resonance spectrometer for operation around 1 MHz with a sub 10 mK noise temperature based on a two stage dc SQUID
L. V. Levitin, R. G. Bennett, A. Casey +5
We have developed a nuclear magnetic resonance spectrometer with a series tuned input circuit for measurements on samples at millikelvin temperatures based on an integrated two-sta…
