ELEKTROKALORISKAIS EFEKTS PEROVSKĪTA STRUKTŪRAS SEGNETOELEKTRIĶOS PIE LIELA ELEKTRISKĀ LAUKA

subject

NBT Elektrokaloriskais efekts Polarizācija Fizika Fāzu pāreja Liels elektriskais lauks

description

Darbā tika pētīts segnetoelektrisko materiālu elektrokaloriskais efekts un dielektriskā polarizācija savienojumos uz Na0.5Bi0.5TiO3 bāzes, galveno uzmanību pievēršot (Na0.5Bi0.5TiO3-BaTiO3)-CaTiO3 cieto šķīdumu sistēmai. Tika noteiktas elektrokaloriskā efekta radītās temperatūras izmaiņas un polarizācijas vērtības atkarībā no temperatūras pie liela elektriskā lauka. Elektrokaloriskā efekta izpēte tika veikta pateicoties jaunizveidotai mērījumu sistēmai. Tika atklāts sastāvs ar lielu un izteiktu elektrokalorisko efektu pie fāzu pārejas temperatūras. Konstatēta netiešās un tiešās elektrokaloriskā efekta metodes savstarpēja neatbilstība.
