Abstract

Electromagnetic composites have wide application in the functional devices. For the best performance of devices, the regulation of the electrical impedance has been being desired for the impedance matching in service. However, the keeping of impedance matching in service is quite challenging. In the present work, a mechanical method for tuning the electrical impedance of La_0.7Sr_0.3MnO₃/0.72Pb(Mg_1/3Nb_2/3)O₃-0.28PbTiO₃ (LSMO/PMN-PT) based on the nanocontact technique is proposed. It is found that the electrical impedance reduces with the increase of the nanocontact load. A linear relationship is found between the square of impedance magnitude and the inverse of nanocontact depth. Furthermore, a method for predicting the contact-depth-dependent impedance magnitude of LSMO/PMN-PT is proposed.
