摘要： Magnetometer circuits are disclosed in which a solenoidal sensor coil (3) including a saturable core (2) is provided with a source potential (Vs) to bring the coil towards saturation, followed by deactivation of the potential to the coil. The current through the coil is sensed and the magnetic field effecting the coil may be determined based on the amount of time which is required for the current in the coil to decline from a first level to a second level. A current sensor (4) connected to the sensor coil provides a first output signal in response to the current through the coil increasing to a first value in a first portion of an operational cycle, and provides a second output signal in response to the current through the coil decreasing to a second value. The time period between the first and second output signals from the current sensor is indicative of the magnitude of the field affecting the coil.

摘要： In a bistable magnetic element, a pulse current or a dc-biased high frequency current is supplied to a soft magnetic material (1) which has a helical magnetic anisotropy. As a result, the magnitude of a voltage induced across the soft magnetic material (1) abruptly changes with respect to variation in an external magnetic field.

摘要： A system and method for noiseless measurement of a biomagnetic field uses magnetic field magnitude and gradient measurement at a reference point together with mathematical extrapolation techniques to provide an effectively infinite order gradiometer response from a lower order physical gradiometer. Such a system has the advantages of potentially lower cost, higher accuracy, and easier adjustment and balancing.

摘要： One aspect of the invention is a method of flux conduction comprising providing a structure with anisotropy not purely in the transverse in-plane direction such that flux spreading into the transverse in-plane direction can occur by rotation. Another aspect includes a method for producing a thin film magnetic device capable of conducting signal flux along a first axis, having at least two active magnetic layers for at least one pole, a first of the active magnetic layers having domains which are oriented in a first direction at rest and a second of the active magnetic layers has domains which are oriented in a second direction at rest. The layers are coupled to each other such that signal flux can flow therebetween. In another aspect, a thin film magnetic device having at least one set of magnetic domains is capable of conducting signal flux along a first axis, having at least one set of magnetic domains, a first of the magnetic domains is capable of conducting flux in a first direction at an angle to the first axis, a second of said magnetic domains is capable of conducting flux in a second direction other than the first direction, the domains coupled to each other such that signal flux can flow along the first axis. In yet another aspect, each of the domains of the set is capable of conducting signal flux in a first and a second in-plane direction. Apparatus includes a thin film magnetic recording device having at least one pole with two magnetic layers and capable of conducting signal flux, a first of the magnetic layers having domains oriented in a first direction, a second of said magnetic layers having domains oriented in a second distinct direction, the layers coupled to each other such that signal flux can flow therebetween. The layers may be at right angles to each other, one layer parallel to the axis of signal flux conduction, or may be canted at other angles in symmetry with the axis of signal flux conduction. Another apparatus includes a magnetic conduction path defined by a series of domains, some domains at least capable of rotation into a first low reluctance path, some domains at least capable of rotation into a second low reluctance path.
