Study of the Magnetoelectric Coupling in the Fe-based Double-perovskite YBaCuFeO₅

　The double-layered perovskite YBaCuFeO₅ undergoes a commensurate to incommensurate magnetic transition at about T_N2~175 K. Distinguishing the contributions of both Fe³⁺/Cu²⁺ to the magnetic structures is crucial for the further understanding of the magnetoelectric coupling and the physical properties of YBCFO. Using RIXS on BL12XU, we observed an excitation peak at the pre-edge of Fe K-edge at room temperature.

　We employed X-ray emission spectroscopy (XES) to reveal the hydrogen bonding states of water molecules in the vicinity of self-assembled monolayers (SAMs). Our measurements demonstrated that the hydrogen bonding states of the water molecules depend on the terminal groups of alkanethiols constituting the SAMs. We discuss the hydrogen bonding states of water molecules in the vicinity of the SAMs.
