Re-entrant superconductivity at an oxide heterointerface
D. Maryenko, M. Kawamura, I. V. Maznichenko +7
A magnetic field typically suppresses superconductivity by either breaking Cooper pairs via the Zeeman effect or inducing vortex formation. However, under certain circumstances, a…
Fragile altermagnetism and orbital disorder in Mott insulator LaTiO
I. V. Maznichenko, A. Ernst, D. Maryenko +5
Based on ab initio calculations, we demonstrate that a Mott insulator LaTiO (LTO), not inspected previously as an altermagnetic material, shows the characteristic features of a…
Emerging two-dimensional conductivity at Mott-band insulator interface
I. V. Maznichenko, S. Ostanin, D. Maryenko +6
Intriguingly conducting perovskite interfaces between ordinary band insulators are widely explored, whereas similar interfaces with Mott insulators are still not quite understood.…
Correlations, disorder, and multi-magnon processes in terahertz spin dynamics of magnetic nanostructures: A first-principles investigation
S. Paischer, D. Eilmsteiner, I. Maznichenko +4
Understanding the profound impact of correlation effects and crystal imperfections is essential for an accurate description of solids. Here we study the role of correlation, disord…
Superconductivity at epitaxial LaTiO3-KTaO3 interfaces
D. Maryenko, I. V. Maznichenko, S. Ostanin +7
Design of epitaxial interfaces is a pivotal way to engineer artificial structures where new electronic phases can emerge. Here we report a systematic emergence of interfacial super…
Gate-tuneable and chirality-dependent charge-to-spin conversion in Tellurium nanowires
Francesco Calavalle, Manuel Suárez-Rodríguez, Beatriz Martín-García +10
Chiral materials are the ideal playground for exploring the relation between symmetry, relativistic effects, and electronic transport. For instance, chiral organic molecules have b…
Externally controlled and switchable 2D electron gas at the Rashba interface between ferroelectrics and heavy metals
Thorsten Aull, Igor V. Maznichenko, Sergey Ostanin +2
Strong spin-orbit coupling in noncentrosymmetric materials and interfaces results in remarkable physical phenomena, such as nontrivial spin textures, which may exhibit Rashba, Dres…
Nonlinear Decay of Quantum Confined Magnons in Itinerant Ferromagnets
Kh. Zakeri, A. Hjelt, I. V. Maznichenko +2
Quantum confinement leads to the emergence of several magnon modes in ultrathin layered magnetic structures. We probe the lifetime of these quantum confined modes in a model system…
Atomic scale spectral control of thermal transport in phononic crystal superlattices

We present experimental and theoretical investigations of phonon thermal transport in (LaMnO)/(SrMnO) superlattices (LMO/SMO SLs) with the thickness of individual l…
Perovskite-type cobalt oxide at the multiferroic Co/Pb ZrTiO interface
K. Mohseni, A. Polyakov, H. B. Vasili +13
Magnetic Tunnel Junctions whose basic element consists of two ferromagnetic electrodes separated by an insulating non-magnetic barrier have become intensely studied and used in non…
Ab initio design of quaternary Heusler compounds for reconfigurable magnetic tunnel diodes and transistors
T. Aull, E. Şaşıoğlu, I. V. Maznichenko +4
Reconfigurable magnetic tunnel diodes and transistors are a new concept in spintronics. The realization of such a device requires the use of materials with unique spin-dependent el…
