Abstract
A Y-type hexagonal oxide magnetic material is provided containing at least Fe, Co, and M (where M is at least one of Ba and Sr) as well as O, wherein the relationship of x+3σ≦4 is satisfied, in which x represents the average grain size (μm) of a sintered compact thereof, and σ represents the standard deviation of the grain size. When this material is used for a magnetic body of an inductor element, a high Q factor can be maintained in a high frequency range of not less than 200 MHZ.
