Terahertz radiation driven nonlinear transport phenomena in two-dimensional tellurene

Autor: Mönch, Erwin, Moldavskaya, Mariya D., Golub, Leonid E., Bel'kov, Vasily V., Wunderlich, Jörg, Weiss, Dieter, Gumenjuk-Sichevska, Joanna, Niu, Chang, Ye, Peide D., Ganichev, Sergey D.

Nonlinear electron transport induced by polarized terahertz radiation is studied in two-dimensional tellurene at room temperature. A direct current, quadratic in the radiation's electric field, is observed. Contributions sensitive to radiation helici

Terahertz and gigahertz magneto-ratchets in graphene-based 2D metamaterials

Autor: Hild, Marcel, Mönch, Erwin, Golub, Leonid E., Dmitriev, Ivan A., Yahniuk, Ivan, Amann, Katharina, Amann, Julia, Eroms, Jonathan, Wunderlich, Jörg, Weiss, Dieter, Consejo, Christophe, Bray, Cedric, Maussang, Kenneth, Teppe, Frederic, Gumenjuk-Sichevska, Joanna, Watanabe, Kenji, Taniguchi, Takashi, Ganichev, Sergey D.

We report on the observation and study of the magneto-ratchet effect in a graphene-based two-dimensional metamaterial formed by a graphite gate that is placed below a graphene monolayer and patterned with an array of triangular antidots. We demonstra

Autor: Ulrich Georg, Pfitzner Emanuel, Hoehl Arne, Liao Jung-Wei, Zadvorna Olga, Schweicher Guillaume, Sirringhaus Henning, Heberle Joachim, Kästner Bernd, Wunderlich Jörg, Venkateshvaran Deepak

Publikováno v: Nanophotonics, Vol 9, Iss 14, Pp 4347-4354 (2020)

We present a nanospectroscopic device platform allowing simple and spatially resolved thermoelectric detection of molecular fingerprints of soft materials. Our technique makes use of a locally generated thermal gradient converted into a thermoelectri

Anomalous Nernst effect in Mn$_3$NiN thin films

Autor: Beckert, Sebastian, Godinho, João, Johnson, Freya, Kimák, Jozef, Schmoranzerová, Eva, Zemen, Jan, Šobáň, Zbyněk, Olejník, Kamil, Železný, Jakub, Wunderlich, Joerg, Němec, Petr, Kriegner, Dominik, Thomas, Andy, Goennenwein, Sebastian T. B., Cohen, Lesley F, Reichlová, Helena

The observation of a sizable anomalous Hall effect in magnetic materials with vanishing magnetization has renewed interest in understanding and engineering this phenomenon. Antiferromagnetic antiperovskites are one of emerging material classes that e

Magneto-Seebeck microscopy of domain switching in collinear antiferromagnet CuMnAs

Publikováno v: Phys. Rev. Materials 4, 094413 (2020)

Antiferromagnets offer spintronic device characteristics unparalleled in ferromagnets owing to their lack of stray fields, THz spin dynamics, and rich materials landscape. Microscopic imaging of aniferromagnetic domains is one of the key prerequisite

Quenching of an antiferromagnet into high resistivity states using electrical or ultrashort optical pulses

Autor: Kašpar, Zdeněk, Surýnek, Miloslav, Zubáč, Jan, Krizek, Filip, Novák, Vít, Campion, Richard P., Wörnle, Martin S., Gambardella, Pietro, Marti, Xavier, Němec, Petr, Edmonds, K. W., Reimers, S., Amin, O. J., Maccherozzi, F., Dhesi, S. S., Wadley, Peter, Wunderlich, Jörg, Olejník, Kamil, Jungwirth, Tomáš

Publikováno v: Nat. Electron 4 (2021) 30-37

Ultra-fast dynamics, insensitivity to external magnetic fields, or absence of magnetic stray fields are examples of properties that make antiferromagnets of potential use in the development of spintronic devices. Similar to their ferromagnetic counte

Imaging and writing magnetic domains in the non-collinear antiferromagnet Mn$_{\text{3}}$Sn

Autor: Reichlova, Helena, Janda, Tomas, Godinho, Joao, Markou, Anastasios, Kriegner, Dominik, Schlitz, Richard, Zelezny, Jakub, Soban, Zbynek, Bejarano, Mauricio, Schultheiss, Helmut, Nemec, Petr, Jungwirth, Tomas, Felser, Claudia, Wunderlich, Joerg, Goennenwein, Sebastian T. B.

Harnessing the unique properties of non-collinear antiferromagnets (AFMs) will be essential for exploiting the full potential of antiferromagnetic spintronics. Indeed, many of the effects enabling ferromagnetic spintronic devices have a corresponding
