Fourier-Legendre expansion of the one-electron density-matrix of ground-state two-electron atoms

Sebastien Ragot, Maria Belen Ruiz

The density-matrix rho(r, r') of a spherically symmetric system can be expanded as a Fourier-Legendre series of Legendre polynomials Pl(cos(theta) = r.r'/rr'). Application is here…

Low temperature and high pressure Raman and x-ray studies of pyrochlore TbTiO : phonon anomalies and possible phase transition

Surajit Saha, D. V. S Muthu, Surjeet Singh +8

We have carried out temperature and pressure-dependent Raman and x-ray measurements on single crystals of TbTiO. We attribute the observed anomalous temperature depende…

Strong enhancement of direct magnetoelectric effect in strained ferroelectric-ferromagnetic thin-film heterostructures

N. A. Pertsev, H. Kohlstedt, B. Dkhil

The direct magnetoelectric (ME) effect resulting from the polarization changes induced in a ferroelectric film by the application of a magnetic field to a ferromagnetic substrate i…

Spin-lattice coupling in multiferroic Pb(Fe1/2Nb1/2)O3 thin films

W. Peng, N. Lemée, M. Karkut +7

We have made magnetization and x-ray diffraction measurements on an epitaxial Pb(Fe1/2Nb1/2)O3 200 nm film. From the temperature dependence of the out-of-plane lattice parameter we…

A new temperature scale T* in lead-based relaxor systems

B. Dkhil, P. Gemeiner, A. Al-Barakaty +4

Via a combination of various experimental and theoretical techniques, a peculiar, identical temperature scale T* is found to exist in all complex lead-based relaxor ferroelectrics.…
