Description
Neutron diffraction study was carried out on a single crystal of Ba2Mg2Fe12O22. The magnetic structure of Ba2Mg2Fe12O22 changes at 195 K, collinear ferrimagnet above 195 K and proper helix below 195 K. The helix is propagated along the c-axis by rotations of the large and small spin-bunches. The turn angle of the helix is 59.6 deg at 77 K and rapidly decreases as the temperature approaches 195 K. Results are discussed from a point of view of the exchange interactions. (author)
