Abstract

Ferroelectric BaTiO ₃ and antiferromagnetic BaFeO ₃ are deposited alternatively by a pulsed laser deposition method with the aim of fabricating room-temperature multiferroic materials. X-ray diffraction (XRD) analysis reveals that the superlattice structure is fabricated with a designed periodicity and thin film quality is improved by increasing BaFeO ₃ layers. Ferroelectricity and ferromagnetic properties are examined by the double-wave method (DWM) of D-E hysteresis loops, an XRD dilatometry, and a superconducting quantum interference device magnetometer. Our superlattice thin film shows multiferroicity, i.e., the coexistence of ferroelectricity and ferromagnetism, at room temperature.
