Abstract

[Problem] To provide MnZn soft ferrite with low core loss over a wide temperature range and its production method. [Solution] MnZn soft ferrite comprising main components consisting of 54.0-55.5% by mol of Fe (calculated as Fe<2>O<3>), and 3-7% by mol of Zn (calculated as ZnO), the balance being Mn (calculated as MnO), and a sub-component including 0.25-0.7% by mass of Co (calculated as Co<3>O<4>) in outer percentage to 100% by mass in total of the main components (calculated as the oxides), a ZnO/Fe<2>O<3> molar ratio being 0.0541-0.127, a Co<3>O<4>/Fe<2>O<3> ratio being 0.00450-0.0130, and a (Co<3>O<4>)<2>/ZnO ratio being 0.0135-0.112.
