摘要:
A thin film magnetic head includes an upper core layer and a lower core layer which are made of an Fe—M—O alloy, an Fe—M—T—O alloy or an NI—Fe—X alloy so that the upper core layer has a high saturation magnetic flux density, low coercive force and high resistivity, and the lower core layer has a lower saturation magnetic flux density than the upper core layer, low coercive force, high resistivity, and a low magnetostriction constant. Also the lower core layer is formed so that the thickness gradually decreases toward both side ends, and a gap layer can be formed on the lower core layer to have a uniform thickness. Since the lower core layer is formed by sputtering, a material having excellent soft magnetic material can be used, thereby enabling recording at high frequency.

摘要:
A production method for a spin-valve type magnetoresistive element comprising laminating an antiferromagnetic layer, a pinned magnetic layer, a non-magnetic electrically conductive layer, a free magnetic layer, and a second antiferromagnetic layer. The second antiferromagnetic layer is located on the free magnetic layer and orients the magnetization direction of the free magnetic layer. In this method, a first thermal treatment is performed at a first temperature of ordering a crystal structure of the first antiferromagnetic layer or at a second temperature lower than a second blocking temperature of the second antiferromagnetic layer. After the first thermal treatment, a second thermal treatment is performed at a third temperature lower than a first blocking temperature of the first antiferromagnetic layer but higher than said second blocking temperature of the second antiferromagnetic layer.
摘要:
The present invention provides a spin-valve magnetoresistive sensor comprising at least two ferromagnetic layers including a first and a second ferromagnetic layers. A first antiferromagnetic layer is layered adjacent to the first ferromagnetic layer for increasing the coercive force of the first ferromagnetic layer to pin the magnetization direction of the first ferromagnetic layer. A pair of second antiferromagnetic layers are respectively positioned adjacent to the longitudinal ends of the second ferromagnetic layer. Further, a pair of third ferromagnetic layers are respectively layered adjacent to said pair of second antiferromagnetic layers for inducing magnetic anisotropy to pin the magnetization direction of each third ferromagnetic layer in a direction perpendicular to the pinned magnetization direction of the first ferromagnetic layer, thereby imposing a longitudinal bias on the second ferromagnetic layer to stabilize magnetic domains therein in order to suppress Barkhausen noise. The magnetization direction of the second ferromagnetic layer remains free to rotate in accordance with the direction of an external magnetic field, thereby changing the electrical resistance of the sensor.
