Here we offer a microscopic explanation of this effect, and we propose a closely related dc transport phenomenon—an off-diagonal symmetric conductivity, linear and odd in a magnetic field, which we refer to as linear magnetoconductivity (LMC). Although LMC has the same functional dependence on a magnetic field as the Hall effect, its origin is fundamentally different: LMC requires time-reversal symmetry to be broken even before a magnetic field is applied, and is therefore a sensitive probe of magnetism. We demonstrate LMC in three different ways: via a tight-binding toy model, a density functional theory calculation on MnPSe3, and a semiclassical treatment. The third approach identifies two distinct mechanisms yielding LMC: momentum-dependent band magnetization and Berry curvature. Finally, we propose an experimental geometry suitable for detecting LMC, and we demonstrate its applicability using Landauer-Büttiker simulations. Our results emphasize the importance of measuring the full conductivity tensor in magnetic materials, and they introduce LMC as a new transport probe of symmetry.","lang":"eng"}],"OA_type":"green","language":[{"iso":"eng"}],"month":"10","title":"Linear magnetoconductivity as a probe of time-reversal symmetry breaking","oa":1,"arxiv":1,"_id":"21431","issue":"13","article_number":"134407","citation":{"mla":"Sunko, Veronika, et al. “Linear Magnetoconductivity as a Probe of Time-Reversal Symmetry Breaking.” <i>Physical Review B</i>, vol. 112, no. 13, 134407, American Physical Society, 2025, doi:<a href=\"https://doi.org/10.1103/33ns-8gwj\">10.1103/33ns-8gwj</a>.","chicago":"Sunko, Veronika, C.
