Contents: Magnetic Skyrmions: Creation, Stability and Dynamics
Abstract:
The discovery of room temperature (RT) magnetic skyrmions in multilayer films has spawned a fascinating research field witnessing rapid progress in fundamental science and device applications [1]. A magnetic skyrmion is defined by the topological character of its spin structure, which emerges from the interplay of atomic-scale magnetic interactions. Skyrmions are expected to scale to sub-10 nm sizes, with individual addressability in devices. Here we describe our efforts to unravel the relationship between the properties of magnetic skyrmions, their parent magnetic interactions, and their stability and dynamics in multilayer thin films and devices. We begin by introducing our material platform – Ir/Fe(x)/Co(y)/Pt multilayers – wherein skyrmion properties (e.g. size, density) can be systematically tailored by varying magnetic interactions [2]. Next, we show how interfacial chiral interactions can progressively lead to the emergence of Néel helicity [3, 4], and the evolution of chiral bubbles into skyrmions [4]. Crucially, we clarify that skyrmions and chiral bubbles have distinct creation and annihilation mechanisms, which manifest in contrasting thermodynamic signatures [5]. We then turn to skyrmions in nanodots – wherein zero field stability is achieved by confinement [6]. Ongoing efforts are exploring their potential for realizing tunnel junction devices. Finally, we examine skyrmion dynamics in nanowire devices [7]. Here, we identify distinct skyrmion dynamic regimes, and distinguish intrinsic electrodynamics from geometric and disorder-related effects. We will conclude by outlining the promise of skyrmions towards nextgeneration electronic technologies.

Contents: Superconductivity in YbRh2Si2

Abstract: Cooper pairing of electrons to form a superconductor can occur via multiple mechanisms [1]. The well-established phonon-mediated pairing in conventional superconductors, such as Al and Nb, results in spin-singlet pair wavefunction that has uniform phase over the Fermi surface. Alternative mechanisms, such as superconductivity driven by spin fluctuations, can lead to both spin-singlet and spin-triplet pairs with complex structures in momentum space. Such unconventional pairing is understood to be required for high temperature superconductivity; moreover some of the spin-triplet superconductors are predicted to have exotic topological properties [2]. There are numerous unconventional superconductors among heavy-fermion metals, however the precise pairing state is rarely known unambiguously. The canonical heavy-fermion metal YbRh2Si2 hosts both antiferromagnetic and ferromagnetic fluctuations [3]. It orders antiferromagnetically at 70 mK, but doping allows to tune the magnetism across two antiferromagnetic and one ferromagnetic phase [4]. Evidence for superconductivity and nuclear magnetism below 2 mK have been reported recently from a study of magnetic properties of YbRh2Si2 [5]. Transport measurements in this temperature regime are challenging and I will report on novel SQUID-based techniques we have developed and applied to probe high-quality single crystals of YbRh2Si2 and microstructures machined from such crystals using focussed ion beam. We observe unambiguous signatures of superconductivity, such as quantised persistent currents. A complex phase diagram emerges in magnetic field, demonstrating interplay between superconductivity and magnetism. The observed superconductivity beyond Pauli limit and distinct transport regimes, that potentially represent different superfluid phases, point towards unconventional spin-triplet superconductivity driven by the ferromagnetic fluctuations. This opens an intriguing possibility that YbRh2Si2 is a crystalline topological superconductor, a sought-after material with promising applications in quantum information processing.
