Aginginduced dielectric relaxation in barium titanate ...

In this letter the authors report on the aging effect on the phase transitions and dielectric properties of 1mol% Mndoped BaTiO3 ceramics. Aging the ceramics in the ferroelectric state stimulates a resistance for the orthorhombictetragonal and tetragonalcubic phase transitions, which leads to stabilization of the tetragonal phase over a wider temperature range.
