Cobalt/Cobaltoxide Exchange Bias System for Diluted Ferromagnetic Alloy Films in Superconducting Spin-Valves

SIDORENKO, A. S.; LENK, D.; ZDRAVKOV, V. I.; MORARI, R.; ULLRICH, A.; MÜLLER, C.; KRUG VON NIDDA, H.-A.; HORN, S.; TAGIROV, L. R.; TIDECKS, R. (Springer Nature Switzerland, 2016)

The present work reports on the influence of a Cobalt sublayer on a conventional exchange bias CoOx/Cu41Ni59 interface. For superconducting spintronics the ability to exchange bias diluted ferromagnetic alloys is an essential ...
Critical temperature oscillations and reentrant superconductivity due to the FFLO like state in F/S/F trilayers

KEHRLE, J.; ZDRAVKOV, V. I.; OBERMEIER, G.; GARCIA-GARCIA, J.; ULLRICH, A.; MÜLLER, C.; MORARI, R.; SIDORENKO, A. S.; HORN, S.; TAGIROV, L. R.; TIDECKS, R. (WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim, 2012)

Ferromagnet/Superconductor/Ferromagnet (F/S/F) trilayers, in which the establishing of a Fulde-Ferrell Larkin-Ovchinnikov (FFLO) like state leads to interference effects of the superconducting pairing wave function, form ...
Full-switching FSF-type superconducting spin-triplet magnetic random access memory element

LENK, D.; MORARI, R.; ZDRAVKOV, V. I.; ULLRICH, A.; KHAYDUKOV, Yu; OBERMEIER, G.; MÜLLER, C.; SIDORENKO, A. S.; NIDDA von, H.-A. Krug; HORN, S.; TAGIROV, L. R.; TIDECKS, R. (American Physical Society, 2017)

In the present work a superconducting Co/CoOx/Cu41Ni59/Nb/Cu41Ni59 nanoscale thin film heterostructure is investigated, which exhibits a superconducting transition temperature, Tc, depending on the history of magnetic field ...
Influence of the FFLO-like state on the upper critical field of a superconductor/ferromagnet bilayer: Angular and temperature dependence

LENK, D.; HEMMIDA, M.; MORARI, R.; ZDRAVKOV, V. I.; ULLRICH, A.; MÜLLER, C.; SIDORENKO, A. S.; HORN, S.; TAGIROV, L. R.; LOIDL, A.; NIDDA Von, H.-A. KRUG; TIDECKS, R. (American Physical Society, 2016)

We investigated the upper critical magnetic field,Hc, of a superconductor-ferromagnet (S/F)bilayer of Nb/Cu41Ni59and a Nb film (as reference). We obtained the dependence ofHc⊥andHc‖(perpendicular and parallel to ...
Interference effects of the superconducting pairing wavefunction due to the Fulde-Ferrell-Larkin-Ovchinnikov like state in ferromagnet/superconductor bilayers

ZDRAVKOV, V. I.; KEHRLE, J.; OBERMEIER, G.; ULLRICH, A.; GSELL, S.; LENK, D.; MÜLLER, C.; MORARI, R.; SIDORENKO, A. S.; RYAZANOV, V. V.; TAGIROV, L. R.; TIDECKS, R.; HORN, S. (IOP Publishing, 2011)

The theoretical description of the Fulde–Ferrell–Larkin–Ovchinnikov like state establishing in nanostructured bilayers of ferromagnetic (F) and superconducting (S) material leads to critical temperature oscillations and ...
Memory effect and triplet pairing generation in the superconducting exchange biased Co/CoOx/Cu41Ni59/Nb/Cu41Ni59 layered heterostructure

ZDRAVKOV, V. I.; LENK, D.; MORARI, R.; ULLRICH, A.; OBERMEIER, G.; MÜLLER, C.; NIDDA Von, H.-A. Krug; SIDORENKO, A. S.; HORN, S.; TIDECKS, R.; TAGIROV, L. R. (AIP Publishing LLC, 2013)

We fabricated a nanolayered hybrid superconductor-ferromagnet spin-valve structure, the resistive state of which depends on the preceding magnetic field polarity. The effect is based on a strong exchange bias (about -2 ...
Observation of an fcc–Co nanolayer grown between CoO and amorphous Si

LENK, D.; ULLRICH, A.; ZDRAVKOV, V. I.; MORARI, R.; SIDORENKO, A. S.; HORN, S.; TIDECKS, R. (Springer Nature Switzerland, 2017)

The thermodynamically crystallographic phase of Co at ambient conditions is hexagonal-close-packed. However, it has been found that given a crystallographic support from a suitable substrate, the high-temperature ...
Reentrant superconductivity and superconducting critical temperature oscillations in F/S/F trilayers of Cu41Ni59/Nb/Cu41Ni59 grown on cobalt oxide

ZDRAVKOV, V. I.; KEHRLE, J.; LENK, D.; OBERMEIER, G.; ULLRICH, A.; MÜLLER, C.; NIDDA Von, H.-A. Krug; MORARI, R.; SIDORENKO, A. S.; TAGIROV, L. R.; HORN, S.; TIDECKS, R. (AIP Publishing LLC, 2013)

Ferromagnet/Superconductor/Ferromagnet (F/S/F) trilayers constitute the core of a superconducting spin valve. The switching effect of the spin valve is based on interference phenomena occurring due to the proximity effect ...
