First principles studies of the Born effective charges and electronic dielectric tensors for the relaxor PMN (PbMg1/3Nb2/3O3)

Narayani Choudhury, R. E. Cohen, Eric J. Walter

We report first principles density functional calculations of the Born effective charges and electronic dielectric tensors for the relaxor PMN (PbMg1/3Nb2/3O3). Visualization of th…

Lattice vibrations in high-pressure phases of LiYF

A. Sen, S. L. Chaplot, R. Mittal

Possible variations in the dynamical behaviour of LiYF due to its several structural changes under pressure are examined by making use of the complementary techniques of quas…
