摘要：

This letter reports the E-field tunable behavior of the environmental friendly lead-free perovskite BaZrxTi1-xO3 (x=0.50 and 0.60) relaxor ceramics in the temperature range from 300 to 30 K. dc electric field dependence of dielectric behavior of the ceramics has been studied. The results have been analyzed in relation to tunability (%) and K factor of the tunable dielectric materials. It is shown that manipulating the Zr:Ti concentration in BaZrxTi1-xO3 ceramics and optimizing the applied dc bias field the properties for specific applications in tunable filters, phase shifters, antennas, etc., can be tailored in the temperature range from 100 to 300 K.
