Controlling the magnetic structure in W-type hexaferrites.

ABSTRACT: W-type hexaferrites with varied Co/Zn ratios were synthesized and the magnetic order was investigated using neutron powder diffraction. In SrCo₂Fe₁₆O₂₇ and SrCoZnFe₁₆O₂₇ a planar (Cm'cm') magnetic ordering was found, rather than the uniaxial ordering (P6₃/mm'c') found in SrZn₂Fe₁₆O₂₇ which is common in most W-type hexaferrites. In all three studied samples, non-collinear terms were present in the magnetic ordering. One of the non-collinear terms is common to the planar ordering in SrCoZnFe₁₆O₂₇ and uniaxial ordering in SrZn₂Fe₁₆O₂₇, which could be a sign of an imminent transition in the magnetic structur
