Landau theory and exchange instabilities in Mn$_5$Si$_3$: A case against altermagnetism

Thin-film Mn$_5$Si$_3$ is one of the most studied altermagnetic candidates thanks to its metallicity, demonstrated anomalous transport properties, and assumed $d$-wave exchange splitting pattern enabling spin-polarized transport and vari…
