▎ 摘　　要

NOVELTY - The material has a soft magnetic material and a neodymium iron boron hard magnetic material adhered with a graphene by binder i.e. polyvinyl alcohol. The soft magnetic material is made by mixing of 43-47 pts. wt. Iron(III) oxide, 34-36 pts. wt. manganese(II,III) oxide, 11-13 pts. wt. zinc oxide, 15-22 pts. wt. nickel(II) oxide, 25-30 pts. wt. carbonyl iron powder, 4-7 pts. wt. copper(II) oxide, 0.1-0.5 pts. wt. cobalt(III) oxide, 4-6 pts. wt. barium oxide and proper amount of de-ionized water. A muffle furnace heats mixed material in atmosphere of inert gas e.g. nitrogen gas and oxygen. USE - Liquid added graphene manufacturing additive high-quality magnetic core material. ADVANTAGE - The material improves product density and increases intensity and sensitivity of the soft magnetic material.
