A new magnetic phase in the nickelate perovskite TlNiO
L. Korosec, M. Pikulski, T. Shiroka +5
The RNiO perovskites are known to order antiferromagnetically below a material-dependent Néel temperature . We report experimental evidence indicating the existence…
1D to 2D Na Ion Diffusion Inherently Linked to Structural Transitions in NaCoO
M. Medarde, M. Mena, J. L. Gavilano +9
We report the observation of a stepwise "melting" of the low-temperature Na-vacancy order in the layered transition metal oxide Na0.7CoO2. High-resolution neutron powder diffractio…
Anderson Localization Triggered by Spin Disorder---with an Application to Eu_x Ca_1-x B_6
Daniel Egli, Jürg Fröhlich, Hans-Rudolf Ott
The phenomenon of Anderson localization is studied for a class of one-particle Schrödinger operators with random Zeeman interactions. These operators arise as follows: Static spins…
Magnetic properties of PrCu at high pressure
A. Sacchetti, M. Weller, H. R. Ott +1
We report a study of the low-temperature high-pressure phase diagram of the intermetallic compound PrCu, by means of molecular-field calculations and Cu nuclear-quadr…
Melting of the Na layers in solid Na0.8CoO2
M. Weller, A. Sacchetti, H. R. Ott +2
Data of 23Na NMR spectra- and relaxation measurements are interpreted as suggesting that, upon increasing temperature the Na layers in Na0.8CoO2 adopt a 2D liquid state at T=291 K.…
Pressure induced variation of the ground state of CeAl3
M. Weller, J. L. Gavilano, A. Sacchetti +1
Pressure-induced variations of Al NMR spectra of CeAl indicate significant changes in the ground-state characteristics of this prototypical heavy-electron compound. Prev…
