이방성 및 등방성 Co 합금 박막 매체의 열 안정성을 조사합니다. CoCrTa(Pt)/Cr 매체의 배향 비율은 NiP/Al 기판의 기계적 질감에 의해 제어되었습니다. 벌크 자기 특성, 델타 M 곡선 및 원주 방향 및 방사형 방향의 자화 시간 감쇠를 측정했습니다. 원주 방향의 자화 시간 감쇠로부터 계산된 최대 자기 점도 계수는 기계적으로 텍스처링된 샘플의 경우 반경 방향보다 높았으나 텍스처가 없는 샘플의 경우 양방향에서 유사했습니다. 역방향 자기장이 박막 기록 매체의 감자 자기장 범위에 있을 때 원주 방향의 자기 점도 계수는 반경 방향의 자기 점도 계수보다 작습니다. 이는 이방성 샘플(즉, 배향비가 높은 샘플)이 큰 외부 자기장에 노출되지 않을 때 열적으로 더 안정적이라는 것을 의미합니다.

Abstract: Thermal stability of anisotropic and isotropic Co alloy thin-film media is investigated. The orientation ratio of CoCrTa(Pt)/Cr media was controlled by the mechanical texture of the NiP/Al substrates. Bulk magnetic properties, delta M curves and time decay of magnetization in the circumferential and radial directions were measured. The maximum magnetic viscosity coefficient calculated from the time decay of magnetization in the circumferential direction was higher than that in the radial direction for a mechanically textured sample, while it was similar in both directions for a non-textured sample. The magnetic viscosity coefficient in the circumferential direction is smaller than that in the radial direction when the reverse field is in the range of the demagnetization field for thin-film recording media. This implies that an anisotropic sample (namely, a sample with a high orientation ratio) will be more thermally stable when it is not exposed to a large external magnetic field.
