Magnetic excitations in the half-metallic shandite Co3Sn2S2
Co3Sn2S2 is a metallic ferromagnet with Tc = 177 K, which crystallizes in a shandite-type structure. Below the Curie temperature its electronic structure forms a half-metal... -
Field induced z=2 quantum critical dynamics in a 1d quantum magnet
Quantum phase transitions have recently received a lot of interest in various different fields of physics and the emergent universal properties have been studied in very...
