Monoclinic EuSn2As2: A Novel High-Pressure Network Structure

The layered crystal of EuSn2As2 has a Bi2Te3-type structure in rhombohedral ( R ¯ 3 m ) symmetry and has been confirmed to be an intrinsic magnetic topological insulator at ambient conditions. Combining ab initio calculations and in situ x-ray diffraction measurements, we identify a new monoclinic E...
