Структура, зеренное строение и диэлектрические свойства керамик твердых растворов YCu-=SUB=-x-=/SUB=-Mn-=SUB=-1-x-=/SUB=-O-=SUB=-3-=/SUB=-

Solid solution ceramics of the YCuxMn1-xO3 system at x = 0.05; 0.10; 0.15 were prepared by solid-phase reactions followed by sintering using conventional ceramic technology. The study of their structure, microstructure and dielectric properties including of temperature and frequencies investigation of dielectric permittivity, conductivity and tangent of dielectric loses is carried out. It is established that hexagonal phase is predominantly formed in the ceramics. Its grain structure is unhomogenius, while synthesis is performed with the formation of liquid phases of eutectic origin. It is shown that anomalous behavior of dielectric characteristics at Т=30-200 ºС connected to interlayer polarization effects, while features at Т = 222 ºС (x = 0.05), 234 ºС (x = 0.10) and 247 ºС (x = 0.15) we connected to “isostructural” phase transition that is intermediate between the ferroelectric and paraelectric phases.

Electric Field Driven Interlayer Polarization Effects in Ferromagnetic 2D Van Der Waals Graphene/CrBr3 Heterostructure

<div>2D vdW heterostructures are realized promising in nano-electronics due to their tunable electronic and magnetic behaviour. Modelling of ferromagnet/non-metal combination is worth to study electronic properties. We studied external electric field tuned electronic structure and magnetic moment variation in the framework of ferromagnetic ground state ordering non-spin interaction. The heterostructure system exhibits tenability in electronic bandgap. Similarly, the magnetic moment shows minor fluctuation in its value due to interlayer polarization. This is beneficial to be extended further for interesting quantum behaviour of phase change and suitability of the system in electronic device applications.</div>
