Chiral Spin-Wave Velocities Induced by All-Garnet Interfacial Dzyaloshinskii-Moriya Interaction in Ultrathin Yttrium Iron Garnet Films

Haiming Yu, Song Liu, Peng Gao, Dirk Grundler, Ping Che, Yuehui Li, Sa Tu, Jilei Chen, Jianyu Zhang, Tao Liu

Spin waves can probe the Dzyaloshinskii-Moriya interaction (DMI), which gives rise to topological spin textures, such as skyrmions. However, the DMI has not yet been reported in yttrium iron garnet (YIG) with arguably the lowest damping for spin waves. In ...

Roundtable Panel Discussion at DAC 2019: Evolutionary Computing or Heuristic Forever?

Massimiliano Di Ventra, Giovanni De Micheli

As demands for computing have been continuously increasing, various solutions have been proposed. Some approaches deal with improving algorithms and software programs, mainly through the tuning of advanced heuristics and learning methods. Some other tackle ...

Electronic, excitonic and magnetic properties of two-dimensional heterostructures

Alberto Ciarrocchi

Two-dimensional (2D) crystals such as graphene or transition metal dichalcogenides (TMDCs) are a fascinating class of quantum materials. These compounds are obtained isolating the single atomic sheets that normally form bulk layered crystals, and the reduc ...

Measuring the Intra-Atomic Exchange Energy in Rare-Earth Adatoms

Harald Brune, François Patthey, Stefano Rusponi, Marina Pivetta

We present the first experimental determination of the intra-atomic exchange energy between the inner 4f and the outer 6s5d shells in rare-earth elements. Inelastic electron tunneling spectroscopy on individual rare-earth atoms adsorbed on metal-supported ...

Analogue computing with metamaterials

Romain Christophe Rémy Fleury, Farzad Zangeneh Nejad

Despite their widespread use for performing advanced computational tasks, digital signal processors suffer from several restrictions, including low speed, high power consumption and complexity, caused by costly analogue-to-digital converters. For this reas ...

Spin-Split Band Hybridization in Graphene Proximitized with alpha-RuCl3 Nanosheets

Klaus Kern, Marko Burghard

Proximity effects induced in the two-dimensional Dirac material graphene potentially open access to novel and intriguing physical phenomena. Thus far, the coupling between graphene and ferromagnetic insulators has been experimentally established. However, ...

Fast and ultrafast electron microscopies for skyrmions and plasmonics

Gabriele Berruto

In recent years, topology gained a central role in physics. We learnt that energetics could be often explained better by classes of objects defined by having qualitative differences. In today's jargon, we say they are topologically distinct. The process of ...

Phase control of spin waves based on a magnetic defect in a one-dimensional magnonic crystal

Dirk Grundler, Sho Watanabe

Magnonic crystals are interesting for spin-wave based data processing. We investigate one-dimensional magnonic crystals (1D MCs) consisting of bistable Co20Fe60B20 nanostripes separated by 75 nm wide air gaps. By adjusting the magnetic history, we program ...

Spin transport in topological insulator-based nanostructures

Kristina Vaklinova

With the advent of spintronics, significant research effort is made to realize efficient injection, transport, manipulation, and detection of spin. The material platforms and device architectures suitable for this purpose 3D topological insulators (TIs) ar ...

Thermal spin torques in magnetic insulators

Jean-Philippe Ansermet, Sylvain Bréchet, Haiming Yu, Francesco Antonio Vetrò, Ping Che, Yi Zhang, Sa Tu, Cheng Zhao, Yao Zhang

The damping of spin waves transmitted through a two-port magnonic device implemented on a yttrium iron garnet thin film is shown to be proportional to the temperature gradient imposed on the device. The sign of the damping depends on the relative orientati ...

Spin waves with large decay length and few 100 nm wavelengths in thin yttrium iron garnet grown at the wafer scale

Dirk Grundler

Using conventional coplanar waveguides (CPWs), we excited spin waves with a wavelength λ down to 310 nm in a 200 nm thin yttrium iron garnet film grown by liquid phase epitaxy. Spin-wave transmission was detected between CPWs that we separated by up to 2 m ...
