XANES spectroscopy study of Pb(Ti, Zr)O3 ferroelectric thin films

Mira Mandeljc, Marija Kosec, S. P. Gabuda +3

Thin films of zirconium-rich perovskites Pb1-3x/2 Lax Zr0.65 Ti0.35O3 (PLZT; x=0.095) were studied using X-ray absorption near-edge structure (XANES) spectroscopy. Is shown, that s…

Theory of pattern-formation of metallic microparticles in poorly conducting liquid

I. S. Aranson, M. V. Sapozhnikov

We develop continuum theory of self-assembly and pattern formation in metallic microparticles immersed in a poorly conducting liquid in DC electric field. The theory is formulated…
