Ion-Selective Scattering Studied Using the Variable-Energy Electron Irradiation in the Ba0.2K0.8Fe2As2 Superconductor

Low-temperature variable-energy electron irradiation was used to induce non-magnetic disorder in a single crystal of a hole-doped iron-based superconductor, Ba1-xKxFe2As2, x = 0.80. To avoid systematic errors, the beam energy was adjusted non-consequently ...

Controlling magnetic order, magnetic anisotropy, and band topology in the semimetals Sr(Mn0.9Cu0.1)Sb-2 and Sr(Mn0.9Zn0.1)Sb-2

Yong Liu

Neutron diffraction and magnetic susceptibility studies show that orthorhombic single-crystals of topological semimetals Sr(Mn0.9Cu0.1)Sb-2 and Sr(Mn0.9Zn0.1)Sb-2 undergo three-dimensional C-type antiferromagnetic (AFM) ordering of the Mn2+ moments at T-N ...

London penetration depth of electron-irradiated Ba0.47K0.53Fe2As2

Yong Liu

We have characterized an electron-irradiated Ba0.47K0.53Fe2As2 single-crystal using two different techniques: magneto-optic and microwave measurements. The crystal has been measured before as well as after the 2.5 MeV electron irradiation process. After ir ...

Effect of Dilute Magnetism in a Topological Insulator

Yong Liu

Three-dimensional (3D) topological insulator (TI) has emerged as a unique state of quantum matter and generated enormous interests in condensed matter physics. The surfaces of a 3D TI consist of a massless Dirac cone, which is characterized by the Z(2) top ...

Growth and Characterization of High-Quality YTiO3 Single Crystals: Minimizing Ti4+ Containing Impurities and TiN Formation

Arnaud Magrez, Yong Liu

We report the growth of YTiO3 single crystals using different starting materials with the nominal compositions, (1) stoichiometric YTiO3; (2) oxygen deficient YTiO2.925; (3) oxygen deficient YTiO2.85, and different atmospheres, (1) 97%Ar/3%H2; (2) Ar; (3) ...

High-Temperature Phase Transitions Preceding the Decomposition of Mixed Valence Aluminum Titanate Pseudobrookite

Henrik Moodysson Rønnow, Arnaud Magrez, Ivica Zivkovic, Yong Liu, Davor Tolj, Wen Hua Bi

Dark blue single crystals of Al1.753+Ti1.04+Ti0.253+O5 were grown with a novel synthesis method based on the reaction of a Ti3+/Ti4+-containing langbeinite melt and porous alpha-alumina crucible. The obtained needles crystallize in the pseudobrookite struc ...
