## Description

- description: Using a realistic model relevant to La2CuO4 and other altermagnetic
    perovskite oxides, we study interrelations between weak ferromagnetism (WF), anomalous
    Hall effect (AHE), and net orbital magnetization (OM). All of them can be linked
    to the form of Dzyaloshinskii-Moriya (DM) interactions. Nevertheless, while spin
    WF is induced by the DM vector components having the same sign in all equivalent
    bonds, AHE and OM are related to alternating-sign components, which do not contribute
    to any canting of spins. The microscopic model remains invariant under the symmetry
    operation combining the shift of antiferromagnetically coupled sublattices to
    each other with the spin flip. Thus, the band structure remains Kramers-degenerate,
    but the time-reversal symmetry is broken, providing a possibility to realize AHE
    in antiferromagnetic substances. The altermagnetic splitting of bands, breaking
    this symmetry, does not play a major role in the problem. More important is the
    orthorhombic strain, responsible for finite values of AHE and OM.
