Dielectric characterization of multiferroic magnetoelectric double-perovskite Y(Ni0.5Mn0.5)O3 thin films
Applied Physics Letters(2016)
摘要
We report on the functional properties of the Y(Ni0.5Mn0.5)O3 epitaxial thin films, growth by pulsed laser deposition, observing the clear features of their ferroelectric and ferromagnetic nature at cryogenic temperature. The characterization of temperature-dependent complex impedance spectroscopy has shown a dielectric anomaly around the ferromagnetic Curie temperature (≈100 K) indicative of coupling between magnetic and electric orders.
