Abstract—
Single-phase, impurity-free barium neodymium ferroniobate (Ba2NdFeNb4O15) films ~660 nm in thickness have been grown on a Pt(001)/MgO(001) substrate using rf cathode sputtering in an oxygen atmosphere. According to X-ray diffraction data, the films are c-axis-oriented. Two phase transformations have been identified in the Ba2NdFeNb4O15 films in the temperature range from –190 to 200°C: paraelectric → ferroelectric and ferroelectric → ferroelectric. The Ba2NdFeNb4O15 films have been shown to have high room-temperature energy efficiency. The mechanisms underlying the observed effects are discussed and potential applications of barium neodymium ferroniobate nanofilms are analyzed.
