Revealing the Altermagnetism in Hematite via XMCD Imaging and Anomalous Hall Electrical Transport
Edgar Galindez-Ruales, Rafael Gonzalez-Hernandez, Christin Schmitt +16
Altermagnets are a class of magnetic materials that exhibit unconventional transport properties, such as an anomalous Hall effect, despite having compensated sublattice magnetic mo…
Electrical coupling of superparamagnetic tunnel junctions mediated by spin-transfer-torques
Leo Schnitzspan, Mathias Kläui, Gerhard Jakob
In this work, the effect of electrical coupling on stochastic switching of two in-plane superparamagnetic tunnel junctions (SMTJs) is studied, using experimental measurements as we…
Magneto-Optical Imaging of Magnetic-Domain Pinning Induced by Chiral Molecules
Yael Kapon, Fabian Kammerbauer, Shira Yochelis +2
Chiral molecules have the potential for creating new magnetic devices by locally manipulating the magnetic properties of metallic surfaces. When chiral polypeptides chemisorb onto…
Observation of time-reversal symmetry breaking in the band structure of altermagnetic RuO
O. Fedchenko, J. Minar, A. Akashdeep +20
Altermagnets are an emerging third elementary class of magnets. Unlike ferromagnets, their distinct crystal symmetries inhibit magnetization while, unlike antiferromagnets, they pr…
Nonlinear terahertz Néel spin-orbit torques in antiferromagnetic MnAu
Yannic Behovits, Alexander L. Chekhov, Stanislav Yu. Bodnar +8
Antiferromagnets have large potential for ultrafast coherent switching of magnetic order with minimum heat dissipation. In novel materials such as MnAu and CuMnAs, electric rat…
Fiber-tip spintronic terahertz emitters
Felix Paries, Nicolas Tiercelin, Geoffrey Lezier +12
Spintronic terahertz emitters promise terahertz sources with an unmatched broad frequency bandwidth that are easy to fabricate and operate, and therefore easy to scale at low cost.…
