Superconductivity in Compositionally-Complex Cuprates with the YBaCuO Structure
Aditya Raghavan, Nathan Arndt, Nayelie Morales-Colón +8
High-temperature superconductivity is reported in a series of compositionally-complex cuprates with varying degrees of size and spin disorder. Three compositions of Y-site alloyed…
Band Structure and Polarization Effects in Photothermoelectric Spectroscopy of a Bi2Se3 Device
Seyyedesadaf Pournia, Giriraj Jnawali, Ryan F. Need +3
Bi2Se3 is a prototypical topological insulator which has a small band gap (~0.3 eV) and topologically protected conducting surface states. This material exhibits quite strong therm…
Strong Ferromagnetism Achieved via Breathing Lattices in Atomically Thin Cobaltites
Sisi Li, Qinghua Zhang, Shan Lin +22
Low-dimensional quantum materials that remain strongly ferromagnetic down to mono layer thickness are highly desired for spintronic applications. Although oxide materials are impor…
Anomalous Hall and Nernst effects in epitaxial films of topological kagome magnet Fe3Sn2
Durga Khadka, T. R. Thapaliya, Sebastian Hurtado Parra +4
The topological kagome magnet (TKM) Fe3Sn2 exhibits unusual topological properties, flat electronic bands, and chiral spin textures, making it an exquisite materials platform to ex…
High quality epitaxial thin films and exchange bias of antiferromagnetic Dirac semimetal FeSn
Durga Khadka, T. R. Thapaliya, Jiajia Wen +2
FeSn is a topological semimetal (TSM) and kagome antiferromagnet (AFM) composed of alternating Fe3Sn kagome planes and honeycomb Sn planes. This unique structure gives rise to exot…
Correlating magnetic structure and magnetotransport in semimetal thin films of EuSmTiO
Zach Porter, Ryan F. Need, Kaveh Ahadi +6
We report on the evolution of the average and depth-dependent magnetic order in thin film samples of biaxially stressed and electron-doped EuTiO for samples across a doping ran…
Spin Seebeck imaging of spin-torque switching in antiferromagnetic Pt/NiO heterostructures
Isaiah Gray, Takahiro Moriyama, Nikhil Sivadas +10
As electrical control of Néel order opens the door to reliable antiferromagnetic spintronic devices, understanding the microscopic mechanisms of antiferromagnetic switching is cruc…
Resolving interfacial charge transfer in titanate superlattices using resonant X-ray reflectometry
R. F. Need, P. B. Marshall, E. Weschke +6
Charge transfer in oxide heterostructures can be tuned to promote emergent interfacial states, and accordingly, has been the subject of intense study in recent years. However, acce…
Revealing Optical Transitions and Carrier Recombination Dynamics within the Bulk Band Structure of Bi2Se3
Giriraj Jnawali, Samuel Linser, Iraj Abbasian Shojaei +5
Bismuth selenide (Bi2Se3) is a prototypical three-dimensional topological insulator whose Dirac surface states have been extensively studied theoretically and experimentally. Surpr…
Magnetoentropic signatures of skyrmionic phase behavior in FeGe
Joshua D. Bocarsly, Ryan F. Need, Ram Seshadri +1
We demonstrate that magnetocaloric measurements can rapidly reveal details of the phase diagrams of high-temperature skyrmion hosts, concurrently yielding quantitative latent heats…
Interface-driven ferromagnetism within the quantum wells of a rare earth titanate superlattice
R. F. Need, B. J. Isaac, B. J. Kirby +3
Here we present polarized neutron reflectometry measurements exploring thin film heterostructures comprised of a strongly correlated Mott state, GdTiO, embedded with SrTiO…
