Emergent Phenomena Induced by Spin-Orbit Coupling at Surfaces and Interfaces
Anjan Soumyanarayanan, Nicolas Reyren, Albert Fert +1
Spin-orbit coupling (SOC) describes the relativistic interaction between the spin and momentum degrees of freedom of electrons, and is central to the rich phenomena observed in con…
A versatile rotary-stage high frequency probe station for studying magnetic films and devices
Shikun He, Zhaoliang Meng, Lisen Huang +3
We present a rotary-stage microwave probe station suitable for magnetic films and spintronic devices. Two stages, one for field rotation from parallel to perpendicular to the sampl…
Tunable Room Temperature Magnetic Skyrmions in Ir/Fe/Co/Pt Multilayers
Anjan Soumyanarayanan, M. Raju, A. L. Gonzalez Oyarce +9
Magnetic skyrmions are nanoscale topological spin structures offering great promise for next-generation information storage technologies. The recent discovery of sub-100 nm room te…
A broadband Ferromagnetic Resonance dipper probe for magnetic damping measurements from 4.2 K to 300 K
Shikun He, Christos Panagopoulos
A dipper probe for broadband Ferromagnetic Resonance (FMR) operating from 4.2 K to room temperature is described. The apparatus is based on a 2-port transmitted microwave signal me…
Observation of a 4-spin Plaquette Singlet State in the Shastry-Sutherland compound SrCu2(BO3)2
Mohamed E. Zayed, Christian Rüegg, Julio Larrea +17
The study of interacting spin systems is of fundamental importance for modern condensed matter physics. On frustrated lattices, magnetic exchange interactions cannot be simultaneou…
A disorder-enhanced quasi-one-dimensional superconductor
A. P. Petrović, D. Ansermet, D. Chernyshov +6
A powerful approach to analysing quantum systems with dimensionality involves adding a weak coupling to an array of one-dimensional (1D) chains. The resultant quasi-one-dimen…
Interfacial effects revealed by ultrafast relaxation dynamics in BiFeO/YBaCuO bilayers
D. Springer, Saritha K. Nair, Mi He +6
The temperature dependence of the relaxation dynamics in the bilayer thin film heterostructure composed of multiferroic BiFeO (BFO) and superconducting YBaCuO$_{7…
Hysteretic magnetoresistance and unconventional anomalous Hall effect in the frustrated magnet TmB_4
Sai Swaroop Sunku, Tai Kong, Toshimitsu Ito +4
We study TmB_4, a frustrated magnet on the Archimedean Shastry-Sutherland lattice, through magnetization and transport experiments. The lack of anisotropy in resistivity shows that…
