摘要：
The paper discuses synthesis and magnetodielectric properties of La0.67Sr0.33MnO3 (LSMO), Ba0.7Sr0.3TiO3 (BST), and BST/LSMO thin film heterostructures. The XRD spectra are determined for confirmation of the crystal structure of LSMO, BST and formation of a pure bi-phase composite. The paper presents variation of Cp and tan delta as a function of frequency between 100 Hz to 1 MHz and applied magnetic field up to 0.6 T. The observed variation of Cp, tan delta, magnetocapacitance and impedance spectra are analyzed in terms of a possible equivalent circuit model. The present analysis shows that the method of impedance spectra could be used to separate out the possible contributions.
