Optimizing the flux coupling between a nanoSQUID and a magnetic particle using atomic force microscope nanolithography
Marc Faucher, Pierre-Olivier Jubert, Olivier Fruchart +2
We present results of Niobium based SQUID magnetometers for which the weak-links are engineered by the local oxidation of thin films using an Atomic Force Microscope (AFM). Firstly…
Nodeless spin triplet superconducting gap in Sr2RuO4
H. Suderow, V. Crespo, I. Guillamon +5
We report on tunneling spectroscopy measurements using a Scanning Tunneling Microscope (STM) on the spin triplet superconductor Sr2RuO4. We find a negligible density of states clos…
Scanning tunneling spectroscopy with superconducting tips of Al
I. Guillamon, H. Suderow, S. Vieira +1
We present Scanning Tunneling Spectroscopy measurements at 0.1 K using tips made of Al. At zero field, the atomic lattice and charge density wave of 2HNbSe2 are observed, and under…
The Fincher-Burke spin excitations and omega/T scaling in the insulating 5% Sr-doped La2CuO4
Wei Bao, Ying Chen, K. Yamada +4
Insulating La1.95Sr0.05CuO4 shares with superconducting cuprates the same Fincher-Burke-like spin excitations, which usually are observed in itinerant antiferromagnets. The local s…
Thermodynamics of a Heavy Ion-Irradiated Superconductor: the Zero-Field Transition
C. J. van der Beek, Thierry Klein, René Brusetti +4
Specific heat measurements show that the introduction of amorphous columnar defects considerably affects the transition from the normal to the superconducting state in zero magneti…
