Andreev experiments on superconductor/ferromagnet point contacts
S. Bouvron, M. Stokmaier, M. Marz +1
Andreev reflection is a smart tool to investigate the spin polarisation P of the current through point contacts between a superconductor and a ferromagnet. We compare different mod…
Approaching quantum criticality in a partially geometrically frustrated heavy-fermion metal
V. Fritsch, N. Bagrets, G. Goll +5
Quantum phase transitions have captured the interest of a large community in condensed-matter and atom physics research. The common feature of these very different material classes…
Experimental verification of contact-size estimates in point-contact spectroscopy on superconductor/ferromagnet heterocontacts
J. Gramich, P. Brenner, C. Sürgers +2
Nanostructured superconductor/ferromagnet heterocontacts are studied in the different transport regimes of point-contact spectroscopy. Direct measurements of the nanocontact size b…
A second superconducting energy gap of Nb_3Sn observed by breakjunction point-contact spectroscopy
M. Marz, W. Goldacker, R. Lortz +1
We report on investigations of the superconducting energy gap of the A15 superconductor Nb_3Sn by point-contact spectroscopy of breakjunctions. The voltage-dependent differential c…
Point-contact spectroscopy in heavy-fermion superconductors
Mikael Fogelström, W. K. Park, L. H. Greene +2
We develop a minimal model to calculate point-contact spectra between a metallic tip and a superconducting heavy-fermion system. We apply our tunneling model to the heavy fermion C…
A Scanning Tunneling Microscope for a Dilution Refrigerator
M. Marz, G. Goll, H. v. Loehneysen
We present the main features of a home-built scanning tunneling microscope that has been attached to the mixing chamber of a dilution refrigerator. It allows scanning tunneling mic…
