TL;DR: In this paper , the anomalous Hall effect in pristine Cr2Te3 thin films manifests a unique temperature-dependent sign reversal at nonzero magnetization, resulting from the momentum-space Berry curvature as established by first-principles simulations.
Structural, electronic, and magnetic properties of <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:msub><mml:mi>CrTe</mml:mi><mml:mn>2</mml:mn></mml:msub></mml:math>
TL;DR: In this paper , the magnetic anisotropy of two-dimensional chromium ditelluride (CrTe2) was derived from the large spin orbit coupling of the Te atoms and the anisotropic of the exchange coupling constants in an XXZ type Hamiltonian.
Andreev processes in mesoscopic multiterminal graphene Josephson junctions
Fan Zhang,Asmaul Smitha Rashid,Mostafa Tanhayi Ahari,Wei Zhang,Krishnan Mekkanamkulam Ananthanarayanan,Run Xiao,George de Coster,Matthew J. Gilbert,Nitin Samarth,Morteza Kayyalha +9 more
TL;DR: In this article , the authors investigated the resonant Andreev reflection processes in the differential resistance maps of four-terminal Josephson junctions and showed that they can be distinguished from the expected current-phase relation for multiplet Cooper pairings.

Growth and Magnetotransport in Thin Film {\alpha}-Sn on CdTe
TL;DR: In this article, the authors report growth and characterization of epitaxial thin films grown on CdTe(111)B. Noninvasive techniques verify the film's pseduomorphic growth before fabrication of magnetotransport devices, overcoming ex-situ obstacles on uncapped films for measurement in the Hall bar geometry.

Reconfigurable magnetic-field-free superconducting diode effect in multi-terminal Josephson junctions
Fan Zhang,Mostafa Tanhayi Ahari,Asmaul Smitha Rashid,George de Coster,Takashi Taniguchi,Kenji Watanabe,Matthew J. Gilbert,Nitin Samarth,Morteza Kayyalha +8 more
TL;DR: In this paper , a materials-agnostic and magnetic-free approach based on four-terminal Josephson junctions (JJs) was proposed to engineer a superconducting diode with SDE.
