Abstract:	High-frequency magnetic properties at K and Ka bands (18-40 GHz) have been studied for M-type barium ferrite BaMn xTi xFe 12-2xO 19 (x=0.4-1.0) composites. The results show that complex permeability of the composites has a resonancelike-type dispersion. Although (μ′ 0-1) is rather small (about 0.2), μ″ max achieves 0.53-0.78, due to small effective damping coefficient. The composites also exhibit relatively high resonance frequencies f R covering 20-33 GHz, which are proportional to anisotropy fields H a of the barium ferrites. These properties will be beneficial to the design of electromagnetic composites at a desired working frequency. © 2012 Elsevier B.V. All rights reserved.
