Anelastic relaxor behavior of Pb(Mg1/3Nb2/3)O3

Relationship between local structure and relaxor behavior in perovskite oxides.

Despite intensive investigations over the past five decades, the microscopic origins of the fascinating dielectric properties of ABO3 relaxor ferroelectrics are currently poorly understood. Here, we show that the frequency dispersion that is the hallmark of relaxor behavior is quantitatively related to the crystal chemical characteristics of the solid solution. Density functional theory is used...

Dielectric relaxation modes in bismuth-doped SrTiO3: The relaxor behavior

The ferroelectric relaxor behavior in Bi-doped SrTiO3 was studied in the temperature range 1.5–300 K and up to 400 MHz. Some interesting results are shown: ~1! Typical ferroelectric relaxor behavior develops out of the other impurity relaxation modes. The ferroelectric relaxor peaks occur on the quantum-paraelectric background. The polarization irreversibility effect observed after field coolin...

Anelastic convection-driven dynamo benchmarks

Benchmark solutions for fully nonlinear anelastic compressible convection and dynamo action in a rotating spherical shell are proposed. Three benchmarks are specified. The first is a purely hydrodynamic case, which is steady in a uniformly drifting frame. The second is a self-excited saturated dynamo solution, also steady in a drifting frame. The third is again a self-excited dynamo but is unst...
