Triple-gap superconductivity of MgB2 - (La,Sr)MnO3 composite. Which of the gaps is proximity induced?
V. N. Krivoruchko, V. Yu. Tarenkov
Interplay of superconductivity and magnetism in a composite prepared of the ferromagnetic half-metallic La_0.67Sr_0.33MnO (LSMO) nanoparticles and the conventional s-wave supercond…
Unconventional ferromagnetism and transport properties of (In,Mn)Sb dilute magnetic semiconductor
V. N. Krivoruchko, V. Yu. Tarenkov, D. V. Varyukhin +3
Narrow-gap higher mobility semiconducting alloys In_{1-x}Mn_{x}Sb were synthesized in polycrystalline form and their magnetic and transport properties have been investigated. Ferro…
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…
Point-contact spectroscopy of magnesium diboride with different counter-electrodes
A. I. D'yachenko, V. Yu. Tarenkov, M. A. Belogolovskii +3
We report on tunneling and Andreev-reflection conductance spectra of 39 K superconducting magnesium diboride, obtained with Pb and Au counter-electrodes. Two distinct steps at clos…
ab-plane tunneling and Andreev spectroscopy of superconducting gap and pseudogap in (Bi,Pb)2Sr2Ca2Cu3O10 and Bi2Sr2CaCu2O8
A. I. D'yachenko, V. Yu. Tarenkov, R. Szymczak +4
We have measured the temperature dependence of gap features revealed by Andreev reflection Delta_s and by tunneling Delta in the ab-plane of optimal and slightly overdoped microcry…
Evidence of strong electron-phonon interaction in superconducting MgB from electron tunneling
A. I. D'yachenko, V. Yu. Tarenkov, A. V. Abal'oshev +1
We report tunneling measurements of the electron-phonon (e-ph) interaction in superconducting MgB using the MgB-I-Nb junctions, where I stands for insulator. The phonon str…
