Oxygen isotope effect on the superfluid density within the wave and wave pairing channels of YBaCuO

Rustem Khasanov, Alexander Shengelaya, Kazimierz Conder +3

We report on measurements of the oxygen isotope (O/O) effect (OIE) on the transition temperature and the zero-temperature in-plane magnetic penetration de…

Direct evidence for the emergence of a pressure induced nodal superconducting gap in the iron-based superconductor Ba_0.65Rb_0.35Fe_2As_2

Zurab Guguchia, Alex Amato, Jian Kang +10

Identifying the superconducting (SC) gap structure of the iron-based high-temperature superconductors (Fe-HTS's) remains a key issue for the understanding of superconductivity in t…

Negative Oxygen Isotope Effect on the Static Spin Stripe Order in La_(2-x)Ba_xCuO_4 (x = 1/8)

Z. Guguchia, R. Khasanov, M. Bendele +4

Large negative oxygen-isotope (16O/18O) effects (OIE's) on the static spin-stripe ordering temperature T_so and the magnetic volume fraction V_m were observed in La_(2-x)Ba_xCuO_4…

Lattice and polarizability mediated spin activity in EuTiO_3

K. Caslin, R. K. Kremer, Z. Guguchia +3

EuTiO_3 is shown to exhibit novel strong spin-charge-lattice coupling deep in the paramagnetic phase. Its existence is evidenced by an, until now, unknown response of the paramagne…

Tuning the static spin-stripe phase and superconductivity in La_(2-x)Ba_xCuO_4 (x = 1/8) by hydrostatic pressure

Z. Guguchia, A. Maisuradze, G. Ghambashidze +3

Magnetization and muon spin rotation experiments were performed in La_(2-x)Ba_xCuO_4 (x = 1/8) as a function of hydrostatic pressure up to p = 2.2 GPa. It was found that the magnet…
