ジャーナル オープンアクセスTo take full advantage of the high output of MR head, it is important to optimize the head parameters. Several researchers have calculated the response of an MR element to an external field, but have not devoted sufficient attention to comparing the calculation results and the head characteristics. We investigated an SAL-biased MR head with the design parameters of element height, film thickness, gap length, and flying height, both theoretically and experimentally. The saturation of the head output with the sensing current is well explained by the sensing current density. The average magnetic flux density on the element height increases with a smaller element height. The ratio of the head output to the average magnetic flux density and the sensing current density is almost constant for the element height.抄録全体を表示PDF形式でダウンロード (269K) -

ジャーナル オープンアクセスThe magnetostriction and magnetic softness of rapidly quenched (Tb0.3Dy0.7)Fe2 alloys prepared at various quenching rates were investigated. The magnetic softness of magnetostriction was estimated from both the residual magnetostriction, λR, measured in a remanent state and the phenomenological softness parameter, H'c. The value of λR increases monotonically from 100 × 10-6 to 700 × 10-6 with incresing roll velocity VRoll. The parameter H'c exhibits a maximum of 0.7 kOe at values of VRoll between 15 and 20 m/s. The magnetostriction measured at 20 kOe, λ20k, exhibits abroad minimum as a function of VRoll. Both λ20k and H'c depend mainly on the preferred orientation of the ribbons. A value of 580 × 10-6 for λ// was obtained at 0.5 kOe; this is comparable with the value for a single crystal sample.抄録全体を表示PDF形式でダウンロード (687K)
