Enhancement of multiferroic properties of Pb(Fe1/2Nb1/2)O-3 thin films on SrRuO3 buffered SrTiO3 substrates
(AIP Publishing, 2009-05-01)
We report multiferroic properties of Pb(Fe1/2Nb1/2)O-3 (or PFN) epitaxial thin layers grown on (001), (110), and (111) SrTiO3 substrates with and without a SrRuO3 (SRO) buffer. Our findings are as follows: (i) the constraint ...
Triclinic phase in tilted (001) oriented BiFeO3 epitaxial thin films
(AIP Publishing, 2009-03-01)
We report a triclinic phase in perovskite BiFeO3 (BFO) epitaxial thin films grown on (130) and (120) oriented SrTiO3 substrates. The lattice constants of the BFO thin films changed with tilt of the substrates from (001) ...
Soft phonon columns on the edge of the Brillouin zone in the relaxor PbMg1/3Nb2/3O3
(American Physical Society, 2009-06-10)
We report lattice-dynamical measurements, made using neutron inelastic-scattering methods, of the relaxor perovskite PbMg1/3Nb2/3O3 (PMN) at momentum transfers near the edge of the Brillouin zone. Unusual "columns" of ...
