Laser-Induced Rashba Spin-Orbit Torques in Multiferroic Semiconductor (Ge,Mn)Te

Zeynab Sadeghi, T. Ostatnický, Eva Schmoranzerová, Jozef Kimák et autres

The multiferroic semiconductor GeMnTe exhibits ferroelectricity, strong Rashba spin-orbit coupling, and carrier-mediated magnetic order, making it a unique platform for exploring the interplay among electronic, structural, and magnetic degrees of freedom. In this study, we investigate the ultrafast magnetization dynamics of Ge0.85Mn0.15Te …

Magnetically tunable symmetry-enforced nodal lines producing huge anomalous Hall conductivity in altermagnetic $α$-MnTe

Mathews Benny, Xujia Gong, Amar Fakhredine, Raphaël Salazar et autres

Altermagnetic $α$-MnTe exhibits huge anomalous Hall conductivity (AHC) up to room-temperature together with weak ferromagnetism arising from spin and orbital polarizations. We clarify the origin of the large value of the AHC by identifying two sets of distinct symmetry-enforced nodal lines in …

Floquet topological state induced by light-driven band inversion in SnTe

Frédéric Chassot, Aki Pulkkinen, Geoffroy Kremer, Chennan Wang et autres

Abstract High-intensity coherent light can realize hybrid phases of matter that are not accessible in equilibrium. The coherent interaction between Bloch states and a periodic electric field, which leads to Floquet-engineered band structures, has been extensively discussed in the literature and shown …

Altermagnetic MnTe

G. Springholz, Mahdi Hajloui, Tetiana Zakusylo, Takuya Takashiro et autres

Altermagnets have attracted tremendous interest due to their unique spin-polarized electronic band structure that opens new avenues towards spin electronic devices. Hexagonal MnTe is a particularly strong altermagnet due to its very large spin splitting above 0.5 eV and its magnetic phase …

High magnification optical imaging systems for the characterization of soft X-ray focii

André Al Haddad, Antoine Sarracini, Kirsten Schnorr, Gregor Knopp et autres

We present a series of novel X-ray imaging systems designed specifically for the soft X-ray energy range, optimized for operation in ultra-high-vacuum environments and compactness. These systems achieve micrometre-level spatial resolution with high collection efficiency of visible light by using high numerical …

Thermally-driven reorientation of the Néel vector in altermagnetic MnTe

T. J. Hicken, Klára Uhlířová, Helena Reichlová, Ondřej Caha et autres

Altermagnets are novel magnetic systems that possess a spin-polarized electronic band structure without a net magnetic moment, making them promising for device applications. Hexagonal MnTe, a prototypical altermagnet, arguably exhibits the most properties consistent with theoretical predictions, including an anomalous Hall effect …

Conduction band structure and ultrafast dynamics of ferroelectric α − GeTe ( 111 )

Geoffroy Kremer, Laurent Nicolaï, Frédéric Chassot, Julian Maklar et autres

$\ensuremath{\alpha}\text{\ensuremath{-}}\mathrm{GeTe}(111)$ is a noncentrosymmetric ferroelectric (FE) material for which a significative lattice distortion combined with a strong spin-orbit interaction gives rise to giant Rashba split states in the bulk and at the surface, which have been intensively probed in the occupied valence …

Nanoscale imaging and control of altermagnetism in MnTe

O. J. Amin, A. Dal Din, Evangelos Golias, Y. Niu et autres

Abstract Nanoscale detection and control of the magnetic order underpins a spectrum of condensed-matter research and device functionalities involving magnetism. The key principle involved is the breaking of time-reversal symmetry, which in ferromagnets is generated by an internal magnetization. However, the presence …
