The present disclosure relates to a complex concentrated soft magnetic amorphous alloy with multi-complex quenched-in nuclei and a method for manufacturing the same, and more specifically, to a complex concentrated soft magnetic amorphous alloy which exhibits low coercivity while improving glass forming ability through the design of configurational entropy control complex alloying composition of a first main element group (Fe, Co, Ni), which determines the degree of magnetization as ferromagnetic metallic elements, a second alloying element group (B, Si, P, C), which facilitates amorphous formation, and a third cluster element group (Ca, Cu, Ag), which forms multi-complex quenched-in nuclei, and a method for manufacturing the same.
The complex concentrated soft magnetic amorphous alloy developed in the present disclosure is characterized by having an excellent switching effect in which the alloy is easily magnetized and demagnetized when a magnetic field is applied and removed by implementing low coercivity. In addition, the present disclosure provides guidelines for alloy development to develop a new alloy with excellent functionality realized by applying a complex concentrated alloy design method to amorphous alloy design. In addition, the present disclosure has presented a step of performing a precise heat treatment based on the (time)-(temperature)-(transformation) curve measurement of the manufactured complex concentrated soft magnetic amorphous alloy, thereby presenting a method capable of effectively controlling an amorphous structure control that has been optimized through the existing trial and error method based on the prediction.
