摘要：

The influence of applied static electric fields on the SrTiO3;V4+ Jahn-Teller system has been studied by means of EPR at liquid helium temperatures. The experimental results can be accounted for by considering a 2T2g electronic ground state showing a strong Jahn-Teller interaction with a localized e(g) mode. In the presence of electric fields, the degeneracy of the vibroric ground state is lifted appreciably by strain. This strain results from strong electrostrictive couplings in SrTiO3.
