Andreev Reflection and Long-Range Proximity Effect in Pb/LaCaMnO Point Contacts
V. N. Krivoruchko, V. Yu. Tarenkov, A. I. D'yachenko +1
The Andreev reflection (AR) spectroscopy has been used to probe mutual influence of superconducting pairing and ferromagnetic correlations in contacts of low-temperature supercondu…
Magnetism via superconductivity in SF proximity structures
V. N. Krivoruchko, V. N. Varyukhin
We consider the proximity effects in hybrid superconductor (S) - ferromagnet (F) structures drawing attention to the induced ferromagnetism of the S metal. The analysis is based on…
Enhancement of the Josephson current by magnetic field in superconducting tunnel structures with paramagnetic spacer
V. N. Krivoruchko, E. A. Koshina
The dc Josephson critical current of a (S/M)IS tunnel structure in a parallel magnetic field has been investigated (here S is a superconductor, S/M is the proximity coupled S and p…
Magnetic-field-induced supercurrent enhancement in hybrid superconductor/magnetic metal structures
V. N. Krivoruchko
The dc transport properties of the (S/M)I(M/S) tunnel structure - proximity coupled superconductor (S) and magnetic (M) layers separated by an insulator (I) - in a parallel magneti…
Critical current of a S/F-I-N/S tunnel structure in a parallel magnetic field
V. N. Krivoruchko, E. A. Koshina
We study the critical current of a S/F-I-N/S tunnel structure - a proximity coupled superconductor (S) with thin ferromagnetic (F) and nonmagnetic (N) metals separated by an insula…
