Study on dielectric and magnetodielectric properties of Lu3Fe5O12 ceramics
Polycrystalline Lu3Fe5O12 ceramics with garnet structure were prepared by a solid-state reaction method. A dielectric relaxor behavior at low temperature was observed which may come from the dipolar e...

Spiral nucleation of silicon solidified on heterogeneous surface of carbon nanocones
Molecular dynamics studies are carried out to examine the spiral nucleation mode of silicon solidified on the surface of carbon nanocones (CNCs). The silicon atoms are concentrated to form magic multi...

Permittivity measurements of a 0.93PMN-0.07PT thin film show a broad maximum near 35 °C, and an anomaly at the depolarizing temperature Td=18 °C on heating only, suggesting a dipolar glass-relaxor phase transition. No structural phase transition at 18 °C is apparent from ferroelectric hysteresis loops taken on field cooling and field heating. These loops show the thermal hysteresis expected for ferroelectric relaxors, which has not hitherto been experimentally verified in PbMg2/3Nb1/3O3-PbTiO3 thin films. Our data suggest the intriguing possibility of a giant electrocaloric effect (DeltaT=9  K,  DeltaE=720  kV cm−1) at and near room temperature. ©2009 American Institute of Physics
