摘要：

Various acceptor and donor dopants were incorporated into Ba0.60Sr0.40MxTi1-xO3 and their effect on dielectric properties for the material's use as a phase shifting device was studied. The best combination of high epsilon, low tan delta, and largest DELTAepsilon with applied bias DELTAV, was found in the Fe-doped material. The addition of 1 mol% Ba or Sr to the Fe-doped material was seen to further improve the properties. Other dopants studied included Mn, Bi, Ga, Y, and Nb.
