Giant orbital diamagnetism of three-dimensional Dirac electrons in Sr${}_3$PbO antiperovskite

S. Suetsugu, K. Kitagawa, T. Kariyado +5

In Dirac semimetals, inter-band mixing has been known theoretically to give rise to a giant orbital diamagnetism when the Fermi level is close to the Dirac point. In Bi${}_{1-x}$Sb$…
