Relation between electric phase and magnetic ordering of Y-type Hexaferrite

Y-type hexaferrite Ba$_{0.5}$Sr$_{1.5}$Zn$_{2}$Fe$_{12}$O$_{22}$(BSZFO), one of multiferroic materials, we could acquire magnetic field-induced commensurate phase, changing of magnetic phase of BSZFO and Ba$_{0.5}$Sr$_{1.5}$Zn$_{2}$(Fe$_{1-x}$Al$_{x}$)$_{12}$O$_{22}$ (x = 0.08)(BSZFAO) using resonant soft X-ray scattering(RSXS) experiment. Also we could confirm that magnetic ordering changing has some relation with electric phase transition, q=1.5 at ferroelectric phase not only BSZFO but also BSZFAO. This research results were acquired by using 2A EPU beamline at PAL.
