abstract |
Multiferroic BaSrTiO3/NdBiFeO3 (BST/BNFO) mulilayers with 3 nm and 6 nm layer thickness demonstrate superlattice structure in the XRD patterns. The break of the spin cycloide and interface strain results in ferromagnetic behavior and enhancement of magnetization. The total thickness of BNFO is varied in the range of 50-60 nm, and saturation magnetization is varied in the range of 50-60 emu/cm(3), which is an order of magnitude higher than reported for BaTiO3/BiFeO3 superstructure [1]. Polarization hysteresis loop were obtained by second harmonic generation technique and show significant electro-optical switchability. Both magnetization and ferroelectric polarization possess bulk rather than interface localization. |
