Języki publikacji
Abstrakty
Results of the studies on electrical transport and related relaxation phenomena in ferroelectric BaTiO[3] single crystal are presented. Investigations of polarisation and depolarisation in the samples show an existence of very slow relaxation currents in the material. In the neighbourhood of Curie temperature the relation J [tilde] V[^6/5] is fulfilled. The energy activation calculated from depolarisation currents and electrical conductivity are the same and equal to 0.42eV.
W artykule zostały przedstawione wyniki badań nad przewodnictwem elektrycznym i mechanizmem relaksacji w ferroelektrycznym monokrysztale BaTiO[3]. Badania polaryzacji i depolaryzacji w tym materiale wskazują na występowanie bardzo wolnych prądów relaksacji. W pobliżu punktu Curie spełniony jest związek J [tylda] V[^6/5]. Energie aktywacji wyznaczone z prądów depolaryzacji i przewodnictwa elektrycznego są takie same i równe 0,42eV.
