Spin Textures in 2D Magnets

The continuous reduction of the structural size in nanotechnology slowed down over the last decade, approaching the natural limit of single atoms as building blocks of matter. Therefore, intensive research is directed toward exploring new frontiers, in par ...

Numerical study of fully baffled Super-XL-mode discharges on TCV

Christian Gabriel Theiler, Davide Galassi

We present a numerical study of three fully baffled L-mode TCV discharges with three different values of the outer strike-point major radius/total flux expansion, showing that the beneficial effect of large strike point radius is partially screened in thes ...

Reduction of the lattice strain with increasing field amplitude in polycrystalline BiFeO3

Dragan Damjanovic

As dynamic interfaces in piezoelectric materials, domain walls can greatly impact the functionality under applied external fields. Recently, conductive domain walls have been found to result in Maxwell-Wagner (M-W)-like dispersion of the lattice strain and ...

Challenges and Applications to Operando and In Situ TEM Imaging and Spectroscopic Capabilities in a Cryogenic Temperature Range

Vasiliki Tileli, Martial Duchamp, Reinis Ignatans

In this Account, we describe the challenges and promising applications of transmission electron microscopy (TEM) imaging and spectroscopy at cryogenic temperatures. Our work focuses on two areas of application: the delay of electron-beam-induced degradatio ...

Non-linear Shubnikov-de Haas oscillations in the self-heating regime

Philip Johannes Walter Moll, Matthias Carsten Putzke, Chunyu Guo, Xiangwei Huang, Jonas De Jesus Diaz Gomez

We demonstrate a non-linear measurement scheme of the Shubnikov-de Haas effect based on Joule self-heating that builds on ideas of the 3 ?-method used in thin films. While the temperature dependence of the resistance, R(T), of clean metals at low temperatu ...

Tuning ferromagnetism at room temperature by visible light

László Forró, Endre Horvath, Xavier François Mettan, Bálint Náfrádi, Andrea Pisoni, Massimo Spina, Péter Szirmai

Most digital information today is encoded in the magnetization of ferromagnetic domains. The demand for ever-increasing storage space fuels continuous research for energy-efficient manipulation of magnetism at smaller and smaller length scales. Writing a b ...

Anomalous Nernst effect in Co2MnGa thin films with perpendicular magnetic anisotropy

Jean-Philippe Ansermet, Haiming Yu, Simon Granville, Sa Tu, Junfeng Hu, Yao Zhang, Song Liu

The thermoelectric and transport properties of MgO/Co2MnGa/Pd stacks with perpendicular magnetic anisotropy were measured. For a nominal 3.3 nm Co2MnGa thickness, the anomalous Nernst coefficient and the Nernst angle at room temperature were found to be 0. ...

Determining the phase diagram of atomically thin layered antiferromagnet CrCl3

Dumitru Dumcenco, Marco Gibertini, Zhe Wang

Changes in the spin configuration of atomically thin, magnetic van der Waals multilayers can cause drastic modifications in their opto-electronic properties. Conversely, the opto-electronic response of these systems provides information about the magnetic ...

Observation of two independent skyrmion phases in a chiral magnetic material

Helmuth Berger

Magnetic materials can host skyrmions, which are topologically non-trivial spin textures. In chiral magnets with cubic lattice symmetry, all previously observed skyrmion phases require thermal fluctuations to become thermodynamically stable in bulk materia ...

Magnetic phase diagram of Ca-substituted EuFe2As2

The simultaneous presence of an Fe-related spin-density wave and the antiferromagnetic order of Eu-2(+) moments ranks EuFe2As2 among the most interesting parent compounds of iron-based pnictide superconductors. Here we explore the consequences of the dilut ...
