ELECTRICAL CHARACTERIZATION OF CaBa4SmTi3Nb7O30 FERROELECTRIC CERAMIC

Abstract

Long back when the electronic ceramics were discovered, it must have been difficult for anyone to imagine the extent of their applications. Undoubtedly the scope of these ceramics is unlimited as these materials have been utilized in manufacturing a large number of appliances for daily life in the form of sensors, actuators, ultrasonic motors, thin film hybrid displays, mobile phones, and arrays of material strips to produce electricity during motion of an aeroplane, etc. A wide range of electronic ceramics have been investigated for their properties such as electrical insulation; dielectric properties and such other unique properties as spontaneous polarization, transparency and various barrier layer properties associated with significant resistive or capacitive changes. Ferroelectrics, a special class of piezoelectric materials, have drawn attention of physicists because of their remarkable capacitive and memory features. The groups of physicists and material scientists are working v...
