A first principles study of wurtzite-structure MnO
Priya Gopal, Nicola Spaldin, Umesh. V. Waghmare
We present results of a density functional theory study of MnO in the wurtzite structure. Our motivation is provided by recent experiments reporting ferromagnetism in Mn-doped wurt…

Diffusive phase transitions in ferroelectrics and antiferroelectrics
S. A. Prosandeev, I. P. Raevski, U. V. Waghmare
In this paper, we present a microscopic model for heterogeneous ferroelectric and an order parameter for relaxor phase. We write a Landau theory based on this model and its applica…
