TI - Non-linear properties of BaTiO3 above Tc JO - Ferroelectrics VL - 375 SN - 0015-0193 CY - London [u.a.] PB - Taylor & Francis M1 - PreJuSER-3384 SP - 165 PY - 2008 N1 - Record converted from VDB: 12.11.2012 AB - Although numerous papers on physical properties of the BaTiO3 crystal can be found in literature, there is a lack of tentative studies of its properties in temperature range close to but above T-C. That is why investigations of temperature dependence of the dielectric properties, electrostrictive strain and thermal expansion have been undertaken. Results obtained point to non-linear behaviour of all these properties even tens degrees above TC. Especially the non-linear thermal expansion, first time measured in detail for BaTiO3 above TC, implies the existence of micro/nano-polar regions whose temperature stability and sizes are responsible for temperature hysteresis above T-C.
