Flux growth and magneto-transport properties of cubic antiperovskite Ca 3 PbO single crystals
Materials Research Bulletin（2018）
摘要
•Antiperovskite Ca3PbO is predicted to be a three-dimensional Dirac fermion system.•Cubic crystals, 1 mm in size, were obtained by a Ca-self-flux method.•The crucible and sealing method were critical factors to reduce carrier density.•Shubnikov-de Haas oscillations were clearly observed, indicating its high purity.
