International Symposium on Nuclear Quadrupole Interactions (XVth NQI 99) (15.1999. Leipzig, Germany)Phase transitions in the ferroelectric perovskite BaTiO₃ were studied for ^111In-implanted polycrystalline samples by measuring the electric field gradients by means of Perturbed Angular Correlation spectroscopy. The phase transitions between the orthorhombic double left right arrow rhombohedral double left right arrow tetragonal double left right arrow cubic lattices were investigated in 2 - 10 K steps, for increasing and decreasing temperatures, in order to determine their hysteresis. The transition parameters are compared with results from measurements of the spontaneous polarization, electric susceptibility and neutron scattering.engjournal articlehttp://dx.doi.org/10.1515/zna-2000-1-243https://www.degruyter.com/open access538.9Perturbed angular correlationsBaTi0₃Phase transitionsHysteresis^111 InFísica de materialesFísica del estado sólido2211 Física del Estado Sólido
