Strain analysis of multiferroic BiFeO3-CoFe2O4 nanostructures by Raman scattering
O. Chaix-Pluchery, C. Cochard, P. Jadhav +4
We report a Raman scattering investigation of columnar BiFeO3-CoFe2O4 (BFO-CFO) epitaxial thin film nanostructures, where BFO pillars are embedded in a CFO matrix. The feasibility…

Influence of charged walls and defects on DC resistivity and dielectric relaxation in Cu-Cl boracite
C. Cochard, T. Granzow, C. M. Fernandez-Posada +5
Charged domain walls form spontaneously in Cu-Cl boracite on cooling through the phase transition. These walls exhibit changed conductivity compared to the bulk and motion consiste…
