Abstract

본 발명은 와이 타입 페라이트 제조 방법 및 이에 의해 제조된 와이 타입 페라이트에 관한 것이다. 본 발명은 Ba2Co2-xCuxFe12O22와<sub/>같은 조성식을 갖는 와이 타입 페라이트에 있어서, 상기 x 값의 범위는 0.5 ≤ x ≤ 1.5인 것을 특징으로 하는 와이 타입 페라이트를 제공한다. 본 발명에 의하면, 와이 타입 페라이트에 함유된 코발트 이온의 일부를 구리 이온으로 치환하여 1GHz 이상의 고주파 대역에서도 2 이상의 투자율을 가지는 와이 타입 페라이트를 제조할 수 있기 때문에, 와이 타입 페라이트를 고주파 대역을 필요로 하는 통신 장치의 소재로 사용할 수 있는 효과가 있다.
