A cermet type magnetic material whose essential components are Fe, Co and/or Ni and an oxide ceramic such as SiO, Al2O3, SiO2, MgO or TiO2. This material features large hardness, high saturation magnetic induction, low coercive force and good durability and can readily be produced in the form of thin film on a substrate. Optionally this magnetic material may additionally comprise at least one of Si, B, P and C, or Cr and/or Mn.
