Nanoscale dielectric properties of insulating thin films: From single point measurements to quantitative images [PDF]

open access: yes, 2010
Dielectric relaxation (DR) has shown to be a very useful technique to study dielectric materials like polymers and other glass formers, giving valuable information about the molecular dynamics of the system at different length and time scales.

Microwave Planar Sensors for Fully Characterizing Magneto-Dielectric Materials

open access: yesIEEE Access, 2020
This paper presents two complementary split-ring resonator (CSRR)-based sensors for full characterization of magneto-dielectric materials. The first proposed sensor is designed by loading the microstrip line with a CSRR, while the second one is by ...

Magnetoelectric coupling in MnTiO3 [PDF]

open access: yes, 2011
We give general arguments that show that the linear magnetoelectric effect in antiferromagnetic materials gives rise to a magnetocapacitance anomaly—a divergence of the dielectric constant at the magnetic ordering temperature TN that appears in an ...

Density functional investigations on electronic structures, magnetic ordering and ferroelectric phase transition in multiferroic Bi2NiMnO6

open access: yesAIP Advances, 2012
Using the full-potential linearised augmented-plane wave (FP-LAPW) method based on density functional theory (DFT), we have investigated the electronic structures, the magnetic behavior, and the ferroelectric origin of multiferroic Bi2NiMnO6.

Effect of Temperature on Creeping Flashover Voltage of Nanofilled Oil-Pressboard Insulation

open access: yesIEEE Access, 2020
Creeping flashover (surface discharge) at oil-pressboard interface is considered a serious failure of the insulation system in power transformers. In this paper, creeping flashover voltage at oil-pressboard interface using the concept of nanofluids is ...

Universal Electromagnetic Waves in Dielectric

open access: yes, 2008
The dielectric susceptibility of a wide class of dielectric materials follows, over extended frequency ranges, a fractional power-law frequency dependence that is called the "universal" response.

First-order phase transition and unexpected rigid rotation mode in hybrid improper ferroelectric (La, Al) co-substituted Ca3Ti2O7 ceramics

open access: yesJournal of Materiomics, 2019
Ca3Ti2O7 with Ruddlesden-Popper structure exhibits the largest polarization among the known hybrid improper ferroelectrics. However, the high Curie temperature impedes the thorough study of phase transition through dielectric characterization.
