Proximity effect in [Nb(1.5nm)/Fe(x)]/Nb(50nm) superconducting/ferromagnet heterostructures
Yu. N. Khaydukov, S. Pütter, L. Guasco +5
We have investigated the structural, magnetic and superconducting properties of [Nb(1.5nm)/Fe(x)] superlattices deposited on a thick Nb(50nm) layer. Our investigation showed…
Electronic and vibrational signatures of ruthenium vacancies in SrRuO thin films
Gideok Kim, Y. Eren Suyolcu, J. Herrero-Martin +12
The synthesis of stoichiometric SrRuO thin films has been a challenge because of the high volatility of ruthenium oxide precursors, which gives rise to ruthenium vacancies…
Tunable perpendicular exchange bias in oxide heterostructures
Gideok Kim, Yury Khaydukov, Martin Bluschke +9
The exchange bias effect is an essential component of magnetic memory and spintronic devices. Whereas recent research has shown that anisotropies perpendicular to the device plane…
Selective formation of apical oxygen vacancies in LaSrCuO
Gideok Kim, Georg Christiani, Gennady Logvenov +4
The superconducting properties of high-\tc\ materials are functions of carriers concentration, which is controlled by the concentration of defects including heterovalent cations, i…
Control of dopant crystallinity in electrochemically treated cuprate thin films
Alex Frano, Martin Bluschke, Zhijun Xu +16
We present a methodology based on \textit{ex-situ} (post-growth) electrochemistry to control the oxygen concentration in thin films of the superconducting oxide LaCuO g…
Highly nonlinear magnetoelectric effect in antiferromagnetic Co4Ta2O9 single crystals
Nara Lee, Dong Gun Oh, Sungkyun Choi +10
Strongly correlated materials with multiple order parameters provide unique insights into the fundamental interactions in condensed matter systems and present opportunities for inn…
Magnetic proximity effect in [Nb/Gd] superlattices seen by neutron scattering
Yu. N. Khaydukov, E. A. Kravtsov, V. D. Zhaketov +7
We have used spin-polarized neutron reflectometry to investigate the magnetization profile of superlattices composed of ferromagnetic Gd and superconducting Nb layers. We have obse…
Phase-resolved Higgs response in superconducting cuprates
Hao Chu, Min-Jae Kim, Kota Katsumi +26
In high energy physics, the Higgs field couples to gauge bosons and fermions and gives mass to their elementary excitations. Experimentally, such couplings can be inferred from the…
