Skyrmions in synthetic antiferromagnets and their nucleation via electrical current and ultrafast laser illumination
Roméo Juge, Naveen Sisodia, Joseba Urrestarazu Larrañaga +24
Magnetic skyrmions are topological spin textures that hold great promise as nanoscale information carriers in non-volatile memory and logic devices. While room-temperature magnetic…
Imprint from ferromagnetic skyrmions in an antiferromagnet via exchange bias
Kumari Gaurav Rana, Rafael Lopes Seeger, Sandra Ruiz-Gómez +11
Magnetic skyrmions are topological spin textures holding great potential as nanoscale information carriers. Recently, skyrmions have been predicted in antiferromagnets, with key ad…
Room temperature skyrmions at zero field in exchange-biased ultrathin films
K. Gaurav Rana, A. Finco, F. Fabre +12
We demonstrate that magnetic skyrmions with a mean diameter around 60 nm can be stabilized at room temperature and zero external magnetic field in an exchange-biased Pt/Co/NiFe/IrM…
Magnetic and electrical transport signatures of uncompensated moments in epitaxial thin films of the non-collinear antiferromagnet MnIr
James M. Taylor, Edouard Lesne, Anastasios Markou +13
Non-collinear antiferromagnets, with either an L1 cubic crystal lattice (e.g. MnIr and MnPt) or a D0 hexagonal structure (e.g. MnSn and MnGe),…
Current-Driven Skyrmion Dynamics and Drive-Dependent Skyrmion Hall Effect in an Ultrathin Film
Roméo Juge, Soong-Geun Je, Dayane de Souza Chaves +19
Magnetic skyrmions are chiral spin textures that hold great promise as nanoscale information carriers. Since their first observation at room temperature, progress has been made in…
Epitaxial growth, structural characterization and exchange bias of non-collinear antiferromagnetic MnIr thin films
James M. Taylor, Edouard Lesne, Anastasios Markou +8
Antiferromagnetic materials are of great interest for spintronics. Here we present a comprehensive study of the growth, structural characterization, and resulting magnetic properti…
Pressure-induced superconductivity and topological quantum phase transitions in a quasi-one-dimensional topological insulator: Bi4I4
Yanpeng Qi, Wujun Shi, Peter Werner +8
Superconductivity and topological quantum states are two frontier fields of research in modern condensed matter physics. The realization of superconductivity in topological materia…
Bias dependent features in spin transport as a probe of the conduction band minima in Si
S. Parui, K. G. Rana, T. Banerjee
Unusual features in the bias dependence of spin transport are observed in a Co/Au/NiFe spin valve fabricated on a highly textured Cu(100)/Si(100) Schottky interface, exploiting the…
Probing hot electron transport across an epitaxial Schottky interface of SrRuO3/Nb:SrTiO3
S. Roy, A. M. Kamerbeek, K. G. Rana +2
SrRuO3 (SRO), a conducting transition metal oxide, is commonly used for engineering domains in BiFeO3. New oxide devices can be envisioned by integrating SRO with an oxide semicond…
Comparison of hot-electron transmission in ferromagnetic Ni on epitaxial and polycrystalline Schottky interfaces
S. Parui, K. G. Rana, L. Bignardi +3
The hot-electron attenuation length in Ni is measured as a function of energy across two different Schottky interfaces viz. a polycrystalline Si(111)/Au and an epitaxial Si(111)/Ni…
Hot electron transport in a strongly correlated transition metal oxide
