Abstract: A soft ferrite composition comprises a ferrimagnetic ceramic material having a crystal structure and a dopant in the crystal structure, wherein the ceramic material comprises an oxide including nickel, cobalt, zinc, and iron, wherein the dopant is selected from the group consisting of copper oxides, and wherein the dopant is present in the crystal structure at 0.1 to 20 weight percent based Non a total weight of the composition. The dopant can be CuO. The copper oxide doped Ni—Co—Zn ferrite can be used for very high frequency (VHF) and ultra high frequency (UHF) applications such antennas, isolators, and circulators.
