Surface phase transitions in BiFeO3 below room temperature
R. Jarrier, X. Marti, J. Herrero-Albillos +15
We combine a wide variety of experimental techniques to analyze two heretofore mysterious phase transitions in multiferroic bismuth ferrite at low temperature. Raman spectroscopy,…
Evidence for impurity-induced frustration in La2CuO4
P. Carretta, G. Prando, S. Sanna +3
Zero-field muon spin rotation and magnetization measurements were performed in La2Cu{1-x}MxO4, for 0<x< 0.12, where Cu2+ is replaced either by M=Zn2+ or by M=Mg2+ spinless impurity…
Sharp optical phonon softening close to optimal doping in LaBaCuO
Matteo D'Astuto, Guy Dhalenne, Jeff Graf +6
We report a direct observation of a sharp Kohn-like anomaly in the doubly degenerate copper-oxygen bond-stretching phonon mode occurring at in La$_…
Phonon and crystal field excitations in geometrically frustrated rare earth titanates
T. T. A. Lummen, I. P. Handayani, M. C. Donker +5
The phonon and crystal field excitations in several rare earth titanate pyrochlores are investigated. Magnetic measurements on single crystals of Gd2Ti2O7, Tb2Ti2O7, Dy2Ti2O7 and H…
Ordered spin-ice state in the geometrically frustrated metallic-ferromagnet Sm2Mo2O7
Surjeet Singh, R. Suryanarayanan, R. Tackett +4
The recent discovery of Spin-ice is a spectacular example of non-coplanar spin arrangements that can arise in the pyrochlore A2B2O7 structure. We present magnetic and thermodynamic…
Electronic self-doping of Mo-states in A2FeMoO6 (A=Ca, Sr and Ba) half-metallic ferromagnets - a Nuclear Magnetic Resonance study
M. Wojcik, E. Jedryka, S. Nadolski +6
A systematic study of (A,A')2FeMoO6 (A,A'=Ca, Sr, Ba) ferromagnetic oxides with double perovskite structure has been performed using 95,97Mo and 57Fe NMR spectroscopy. These oxides…
