  • The use of antiferromagnetic materials in spintronic devices has been proposed as an attractive alternative to ferromagnets, but only a few suitable materials are known. Here, the authors synthesize a new antiferromagnet (AFM)—tetragonal epitaxial CuMnAs—and show that it is ideal for spintronic applications.

  • The electronic band structure of (Ga,Mn)As has been debated due to contrasting reports of experimental findings from samples differently synthesized. Nĕmec et al.show that a careful optimization of the synthesis protocol is necessary to evaluate the intrinsic semiconducting and magnetic properties of (Ga,Mn)As.

  • Using photoemission spectroscopy and ab initio calculations, evidence is given of two distinct unconventional mechanisms of lifted Kramers spin degeneracy generated by the altermagnetic phase of centrosymmetric MnTe with vanishing net magnetization.

  • Contrary to ferromagnets, antiferromagnets possess no net magnetic moment, which has limited their applicability as magnetic memory media. Here, the authors demonstrate a heat-assisted multiple-stable memory based on epitaxial thin films of antiferromagnet MnTe with three-fold symmetric anisotropy.

  • Controlling the Néel vector switching is crucial to the antiferromagnetic spintronics but so far limited to 90° reorientations. Here the authors report electrical Néel vector reversal and its detection in a fully compensated collinear antiferromagnet (AF) by exploiting the broken time reversal and spatial inversion symmetries of the AF.
