Abstract
A magnetic alloy raw material is heated and melted to create a melt with floating said raw material by means of electromagnetic field from an inductive type heating coil. The melt is located in between a pair of cupper cooling plates driven by a solenoid coil, and then, splat-cooled below the peritectic point of the raw material by the cooling plates.

A method for producing a magnetic alloy, comprising the steps of:
- heating and melting a magnetic alloy raw material with a peritectic point to create a melt,
- supercooling said melt below said peritectic point of said magnetic alloy raw material so that a temperature of a solid-liquid interface of said melt is set below said peritectic point of said magnetic alloy raw material and a growth rate of a peritectic phase is set larger than a growth rate of a primary phase, and then, solidifying said melt.
An apparatus for producing a magnetic alloy, comprising:
- a heating-melting means to heat and melt a magnetic alloy raw material with a peritectic point to create a melt, and
- a cooling means to supercool said melt below said peritectic point of said magnetic alloy raw material so that a temperature of a solid-liquid interface of said melt is set below said peritectic point of said magnetic alloy raw material and a growth rate of a peritectic phase is set larger than a growth rate of a primary phase, and then, solidifying said melt.
