abstract
It is shown that the flow of electric current in an altermagnet results in the formation of a homogeneous electron spin orientation in the sample. The spin of the conduction electrons generated in altermagnets with $d$-wave spin-momentum couplings, is quadratic in the current magnitude, varies as the second angular harmonic under variation of the current direction and does not require broken inversion symmetry. The effect is thus distinct from conventional current induced spin polarization phenomena which are linear in the current, vary as a first angular harmonic under variation of current direction and require broken inversion symmetry. The current-induced spin orientation in altermagnets is obtained using the kinetic theory for distribution functions in the spin-splitted subbands. It is shown that an application of external magnetic field significantly enhances the electron spin.

Cavity driving induces coherent magnetization and polariton signatures in d-wave altermagnets via selective sublattice coupling in a mean-field Lindblad model.
Slow phonons suppress the spin Edelstein effect in strained Rashba d-wave altermagnets through energy renormalization that collapses the Fermi surface, producing tunable anisotropic depolarization.
Ferromagnetic Ni contacts enable anomalous and nonlinear Hall effects in centrosymmetric CrSb, with Hall-slope sign inversion and bow-tie hysteresis attributed to bulk altermagnetism plus topological surface states.
Green's function calculation of third-order resistivity corrections in a quadratic-spin-texture 2DEG with Kondo impurities shows strong suppression of TK and a critical alpha_cr for Kondo collapse.
