Abstract
We have developed a technique to orient particles of Y-type hexaferrite in which the c axis of the particles is oriented perpendicular to a plane. Disks of oriented Ba₂MnZnFe₁₂O₂₂ particles were characterized in static and dynamic field excitations and exhibited the following properties: 4πMs=2300 G, Ha=9500 G, 4πMeff=4πMs+Ha=11800 G, and Hc=60 Oe. The ferrimagnetic resonance linewidth at 27 GHz measured to be 350 Oe and the g factor approximately equal to 2. The magnetic parameters of the oriented particles were very similar to the bulk parameters previously published.
