Growth and properties of altermagnetic MnTe thin films — •Lukas Stroh, Maik Gaerner, Judith Bünte, Karsten Rott, Jan Schmalhorst, Andreas Hütten, and Günter Reiss — Bielefeld University, Germany

In recent years, a new unconventional magnetic phase, named altermagnetism, has emerged [1]. Such altermagnetic materials combine anisotropic time-reversal symmetry breaking with the vanishing net-magnetization of antiferromagnets. One of the materials in which altermagnetism has been observed in is manganese telluride (MnTe) [2,3]. Here, we systematically investigate the growth of MnTe thin films on SrF₂(111) via magnetron co-sputtering. We analyze how the growth-conditions influence structural and electronic properties, including the spontaneous anomalous Hall effect.
