A coil component including: a magnetic body containing a magnetic material and a resin; a coil buried in the magnetic body; and a pair of outer electrodes electrically connected to the coil. One or more side faces of the magnetic body have a groove, and the groove contains a silicone resin.

The invention provides method for making high coercivity magnetic materials based on FeNi alloys having a L1.sub.0 phase structure, tetratenite, and provides a system for accelerating production of these materials. The FeNi alloy is made by preparing a melt comprising Fe, Ni, and optionally one or more elements selected from the group consisting of Ti, V, Al, B, C, Mo, Ir, and Nb; cooling the melt and applying extensional stress and a magnetic field. This is followed by heating and cooling to form the L10 structure.
