    Abstract

    Mössbauer study on a Y-type hexaferrite Ba 2Mg 2Fe 12O 22 has been conducted by using a single crystal specimen. The spins are in the c-plane down to 60 K. For 18h VI site Fe, the quadrupole shifts and the outermost line width change around 195 K, where the transition from ferrimagnetic to proper screw spin structure takes place. Below 50 K, the spin reorientation transition to a longitudinal conical structure was also recognized. At 16 K, the spins incline about 15° from the c-plane.
