Abstract: Disclosed are a soft magnetic alloy and a wireless charging apparatus including the soft magnetic alloy. The soft magnetic alloy has a chemical formula expressed as Fe100-x-yCuxBy (wherein x ranges from 0.1 at % to 1.7 at % and y ranges from 2.3 at % to 9.6 at %). Without adding any expensive alloying element, only iron (Fe), copper (Cu), and boron (B) are used to obtain a nanocrystalline soft magnetic alloy that has a low coercive force and a high saturation magnetic flux density. The nanocrystalline soft magnetic alloy is applied to a wireless power transmitter and a wireless power receiver. Thereby, it is possible to make a shield member thin and increase a power transmission capacity. The soft magnetic alloy is easily processed into a flake form. The soft magnetic alloy processed in this way is applied to the shield member. Thereby, it is possible to increase permeability in a surface direction.

Abstract: Since the magnetic sheet of the present invention has a much thinner thickness compared to a corresponding conventional magnetic layer and radiator coil material assembly and has no adhesive layer or air layer between the magnetic layer and the radiator, permeability required at the time of charging can be improved, a loss rate can be reduced and high charging efficiency can be obtained. Furthermore, since a band width and a gain rate can be improved, the magnetic sheet can be very usefully applied to wireless charging products which pursue slimming in design.
