Electric/magnetic flux tube on the background of magnetic/electric field [PDF]
Annalen der Physik, 2004 AbstractIt is argued that the phenomenon of a flux tube in quantum chromodynamics is closely connected with a spontaneously symmetry breakdown of gauge theory. It is shown that in the presence of a mass term in the SU(2) gauge theory the Nielsen‐Olesen equations describe the flux tube surrounded by an external field.

Switching and energy-storage characteristics in PLZT 2/95/5 antiferroelectric ceramic system [PDF]
Journal of Advanced Dielectrics, 2016 Switching mechanisms and energy-storage properties have been investigated in (Pb0.98La0.02)(Zr0.95Ti0.05)0.995O3 antiferroelectric ceramics. The electric field dependence of polarization (P–E hysteresis loops) indicates that both the ferroelectric (FE ...

Incorporation of dysprosium ions into PbTiO3 ferroelectric ceramic system [PDF]
Journal of Advanced Dielectrics, 2015 A structural analysis concerning the incorporation of dysprosium into A- and/or B-sites of the lead titanate is shown. The two "boundary" refinements are presented, i.e., Dy2+ substitutes for Pb2+ (Dy3+ substitutes for Ti4+) and Dy3+ substitutes for Pb2+
