In altermagnets [1], spin polarization in both crystal-structure real space and electronic-structure momentum space alternates and, consequently, it enables effects that were believed to be exclusive to ferromagnets. Many of the predicted altermagnetic phenomena [2] await their experimental confirmation.
In this seminar, we will introduce the concept of altermagnets. We will present a magnetotransport characterization of two altermagnetic materials – semiconducting MnTe [3] and metallic RuO2. Furthermore, we will discuss which contributions to the measured transversal and longitudinal signals can be signatures of the unconventional altermagnetic phase. Finally, we will refer to ongoing transport experiments in these materials.
