Unconventional co-existence of insulating nano-regions and conducting filaments in reduced SrTiO3: mode softening, local piezoelectricity and metallicity
Annette Bussmann-Holder, Hugo Keller, Arndt Simon +2
Doped SrTiO3 becomes a metal at extremely low doping concentrations n and is even superconducting with the superconducting transition temperature adopting a dome-like shape with th…
Spin-lattice coupling induced weak dynamical magnetism in EuTiO_3 at high temperatures
Z. Guguchia, H. Keller, R. K. Kremer +5
EuTiO_3, which is a G-type antiferromagnet below T_N = 5.5 K, has some fascinating properties at high temperatures, suggesting that macroscopically hidden dynamically fluctuating w…
Nonlinear pressure dependence of T_N in almost multiferroic EuTiO_3
Z. Guguchia, K. Caslin, R. Kremer +7
The antiferromagnetic (AFM) phase transition temperature T_N of EuTiO_3 has been studied as a function of pressure p. The data reveal a nonlinear dependence of T_N on p with T_N in…
Magnetic phase diagram of low-doped La{2-x}SrxCuO4 thin films studied by low-energy muon-spin rotation
E. Stilp, A. Suter, T. Prokscha +7
The magnetic phase diagram of La2-xSrxCuO4 thin-films grown on single-crystal LaSrAlO4 substrates has been determined by low-energy muon-spin rotation. The diagram shows the same f…
Hybrid paramagnon phonon modes at elevated temperatures in EuTiO3
A. Bussmann-Holder, Z. Guguchia, J. Köhler +3
EuTiO3 (ETO) has recently experienced an enormous revival of interest because of its possible multiferroic properties which are currently in the focus of research. Unfortunately ET…
Evidence for novel polaronic Fermi-liquid in doped oxides
A. S. Alexandrov, Guo-meng Zhao, H. Keller +3
The modern multi-polaron theory predicts a polaronic Fermi-liquid state, but such a state has not been unambigously confirmed by experiment so far. Here we report theoretical and e…
