Embodiments relate to systems and methods for producing magnetic material. The method includes providing a mixture of alloys. The composition of alloy are not particularly limited. The method includes melting the mixture of alloys to arrive at a molten mixture of alloys. The method includes performing a melt-spinning process to rapidly solidify the molten mixture of alloys via a rotatable wheel to arrive at a preliminary metallic ribbon. The preliminary metallic ribbon having an elongated flat body with a bottom side and a top side, the top side opposite to the bottom side. The method includes performing a grain size refinement and uniformity process, the grain size refinement and uniformity process including delivering a first coolant directly to at least a central region of the top side and/or bottom side of the preliminary metallic ribbon to arrive at a final metallic ribbon.
