Temperature-dependent electron-phonon coupling in La_{2−x}Sr_{x}CuO_{4} probed by femtosecond x-ray diffraction

Majed Chergui, Henrik Moodysson Rønnow, Fabrizio Carbone, Paul Beaud, Krunoslav Prsa, Giulia Fulvia Mancini, Mathieu Julien Gino Cottet, Kazimierz Conder

The strength of the electron-phonon coupling parameter and its evolution throughout a solid's phase diagram often determines phenomena such as superconductivity, charge- and spin-density waves. Its experimental determination relies on the ability to distin ...

Field-Induced Quantum Soliton Lattice in a Frustrated Two-Leg Spin-1/2 Ladder

Henrik Moodysson Rønnow, Shuang Wang, Christian Rüegg, Siyuan Wang, Joël Mesot, Kazimierz Conder

Based on high-field 31P nuclear magnetic resonance experiments and accompanying numerical calculations, it is argued that in the frustrated S=1/2 ladder compound BiCu2PO6 a field-induced soliton lattice develops above a critical field of μ0Hc1=20.96(7) T. ...

Surface and bulk electronic structure of the strongly correlated system SmB6 and implications for a topological Kondo insulator

Jan Hugo Dil, Joël Mesot, Kazimierz Conder

Recent theoretical calculations and experimental results suggest that the strongly correlated material SmB6 may be a realization of a topological Kondo insulator. We have performed an angle-resolved photoemission spectroscopy study on SmB6 in order to eluc ...

Spin-gap evolution upon Ca doping in the spin-ladder series Sr(14−x)CaxCu24O41 studied by inelastic neutron scattering

Henrik Moodysson Rønnow, Nikolay Tsyrulin, Kazimierz Conder

The spin-gap evolution upon Ca doping in Sr14-xCaxCu24O41 was systematically investigated using inelastic neutron scattering. We discover that the singlet-triplet spin-gap excitation survives in this series with x up to 13, indicating the singlet dimer gro ...

Helical fluctuations in the Raman response of the topological insulator Bi2Se3

Helmuth Berger, Kazimierz Conder

The topological insulator Bi2Se3 shows a Raman-scattering (RS) response related to topologically protected surface states amplified by a resonant interband transition. Most significantly this signal has a characteristic Lorentzian lineshape and spin-helica ...

High oxygen pressure single crystal growth of highly Ca-doped spin ladder compound Sr14-xCaxCu24O41 (x > 12)

Neda Nikseresht Ghanepour, Shuang Wang, Kazimierz Conder

Large size high-quality Ca-doped Sr14-xCaxCu24O41 (x=12.2, 12.6 and 13) spin ladder superconducting single crystals were grown using a modified mirror floating zone furnace with oxygen pressure up to 35 bar. The qualities of the as-grown single crystals we ...

Direct Observation of Impurity-Induced Magnetism in a Spin-1/2 Antiferromagnetic Heisenberg Two-Leg Spin Ladder

Shuang Wang, Siyuan Wang, Joël Mesot, Kazimierz Conder

Nuclear magnetic resonance and magnetization measurements were used to probe the magnetic features of single-crystalline Bi(Cu1-xZnx)(2)PO6 with 0 < x < 0.05 at temperatures between 2.6 K and 300 K. The simple line shape of the P-31 NMR signals of the pris ...

Low-temperature spin-state transition in LaCoO3 investigated using resonant x-ray absorption at the CoK edge

Marco Grioni, Kazimierz Conder

LaCoO3 displays two broad anomalies in the DC magnetic susceptibility chi(DC), occurring, respectively, around 50 K and 500 K. We have investigated the first of them within the 10 K < T < RT temperature range using Co K alpha(1) x-ray absorption spectrosco ...
