简介 A multiphase ferrite composition includes a primary phase consisting of a MnZn ferrite matrix; and 0.01 to 10 weight percent microscaled inclusion particles comprising an orthoferrite RFeO3 wherein R is a rare earth ion, yttrium iron garnet (YIG), or a combination thereof, wherein the microscaled inclusion particles have an average particle size (D50) of 0.1 micron to 5 microns, and wherein the D50 of the microscaled inclusion particles is smaller than the average particle size (D50) of the MnZn ferrite particles; and optionally 0.01 to 5 weight percent additive; wherein weight percent is based on the total weight of the multiphase ferrite composition. A method of manufacturing the multiphase ferrite composition is also disclosed.
