    Terahertz spectroscopy of central and soft phonon modes in LuFe2O4

    The terahertz dielectric response of LuFe2O4 is investigated by terahertz time-domain spectroscopy over a temperature range of 6–290 K. It is revealed that besides the central mode associated with the charge-orde...

    Preparation of epitaxial orthorhombic YMnO3 thin films and the current–voltage rectifying effect

    Epitaxial orthorhombic YMnO3(YMO) thin films on (001) Nb:SrTiO3(NSTO) substrates were prepared by pulsed laser deposition. The weak ferromagnetism at low temperature, probably ascribed to the stretched Mn-spin co...
