Realization of Z Topological Metal in Single-Crystalline Nickel Deficient NiVSe
Sitaram Ramakrishnan, Shidaling Matteppanavar, Andreas Schonleber +6
Temperature-dependent electronic and magnetic properties are reported for a Z2 topological metal single-crystalline nickel-deficient NiVSe. It is found to crystallize in th…
Coupling between colossal charge density wave ordering and magnetism in Ho2Ir3Si5
Sitaram Ramakrishnan, Jin-Ke Bao, Claudio Eisele +14
Ho2Ir3Si5 belongs to the family of three-dimensional (3D) R2Ir3Si5 (R = Lu, Er and Ho) compounds that exhibit a colossal first-order charge density wave (CDW) transition where ther…
Two pressure-induced structural phase transitions in TiOCl
J. Ebad-Allah, A. Schönleber, S. van Smaalen +7
We studied the crystal structure of TiOCl up to pressures of =25~GPa at room temperature by x-ray powder diffraction measurements. Two pressure-induced structural phase transiti…
Mott-Hubbard gap closure and structural phase transition in the oxyhalides TiOBr and TiOCl under pressure
C. A. Kuntscher, A. Pashkin, H. Hoffmann +9
Pressure-dependent transmittance and reflectance spectra of TiOBr and TiOCl single crystals at room temperature suggest the closure of the Mott-Hubbard gap, i.e., the gap is filled…
Pressure-induced metallization and structural phase transition of the Mott-Hubbard insulator TiOBr
C. A. Kuntscher, S. Frank, A. Pashkin +9
We investigated the pressure-dependent optical response of the low-dimensional Mott-Hubbard insulator TiOBr by transmittance and reflectance measurements in the infrared and visibl…
