Neutron pair distribution function analysis and first principles calculations have been employed to study short-range correlations in heavily disordered dielectric material Sr$_x$Ba$_{1-x}$Nb$_2$O$_6$ ($x=0.35, 0.5$ and 0.61). The combination of meth

Band structure of CuMnAs probed by optical and photoemission spectroscopy

Publikováno v: Phys. Rev. B 97, 125109 (2018)

Tetragonal phase of CuMnAs progressively appears as one of the key materials for antiferromagnetic spintronics due to efficient current-induced spin-orbit torques whose existence can be directly inferred from crystal symmetry. Theoretical understandi

Antiferrodistortive phase transition in EuTiO3

Autor: Goian, V., Kamba, S., Pacherova, O., Drahokoupil, J., Palatinus, L., Dusek, M., Rohlicek, J., Savinov, M., Laufek, F., Schranz, W., Fuith, A., Kachlik, M., Maca, K., Shkabko, A., Sagarna, L., Weidenkaff, A., Belik, A. A.

X-ray diffraction, dynamical mechanical analysis and infrared reflectivity studies revealed an antiferrodistortive phase transition in EuTiO3 ceramics. Near 300K the perovskite structure changes from cubic Pm-3m to tetragonal I4/mcm due to antiphase

The two-fold superstructure of titanium(III)-oxybromide at T = 17.5 K

Autor: Palatinus, L., Schoenleber, A., van Smaalen, S.

Publikováno v: Acta Crystallographica (2005). C61, i47-i48

The low-temperature (T = 17.5 K) structure of titanium(III)-oxybromide, TiOBr, is reported as a two-fold superstructure of the crystal structure at room temperature. Weak superlattice reflections could be measured with synchrotron radiation x-rays, a

Spin-Peierls transition in TiOCl

Autor: Shaz, M., van Smaalen, S., Palatinus, L., Hoinkis, M., Klemm, M., Horn, S., Claessen, R.

Publikováno v: Phys. Rev. B 71, 100405(R) (2005)

Temperature-dependent x-ray diffraction of the low-dimensional spin 1/2 quantum magnet TiOCl shows that the phase transition at T_{c2} = 90 K corresponds to a lowering of the lattice symmetry. Below T_{c1} = 66 K a twofold superstructure develops, th
