Embodiment Construction

[0034] Since the invention allows for variations and many embodiments, specific embodiments will be illustrated in the drawings and described in detail. However, this is not intended to limit the present invention to a specific mode of practice, and it should be understood that all changes, equivalents and substitutions that do not depart from the spirit and technical scope of the present invention are included in the present invention.

[0035] Although terms including ordinal numbers such as 'first', 'second', etc. may be used to describe various components, the components should not be limited by the above terms. The above terms are only used to distinguish one component from another. For example, a first element could be termed a second element, and, similarly, a second element could be termed a first element, without departing from the scope of the present invention. The term "and / or" includes any and all combinations of one or more of the associated listed items.

Abstract

According to one embodiment of the present invention, a soft magnetic alloy has a composition of the following chemical formula.[chemical formula] FeaXbYcZd, in which: X comprises silicon (Si) and / orphosphorus (P); Y comprises carbon (C); Z comprises at least one of boron (B), nitrogen (N), aluminum (Al), titanium (Ti), zirconium (Zr), hafnium (Hf), niobium (Nb), tantalum (Ta), chromium (Cr), molybdenum (Mo), cobalt (Co) and nickel (Ni); a is 78-95.75 at%; b is 2-16 at%; c is 2-8 at%; and d is 0.25-10 at%.

Description

technical field [0001] The present invention relates to a soft magnetic alloy, and more particularly relates to an amorphous or nanocrystalline soft magnetic alloy. Background technique [0002] Recently, there has been an increasing demand for high-performance soft magnetic materials to be used in various electronic equipment such as computers, machines, and communication equipment. Therefore, in order to achieve physical properties that cannot be provided by existing materials such as silicon steel and ferrite, it is highly desirable to use high-performance soft magnetic metal materials. Soft magnetic metallic materials with characteristics of high saturation magnetic flux density, high magnetic permeability, and resistivity can be used for general purposes, and can achieve characteristics such as small size, light weight, and low loss by replacing existing components. In particular, high-performance soft magnetic materials can be applied to soft magnetic cores such as in...
