    摘要： According to one embodiment, a magnetic sensor includes a first sensor part. The first sensor part includes a first magnetic member, a first counter magnetic member, and a first magnetic element. A direction from the first magnetic member toward the first counter magnetic member is along a first direction. The first magnetic element includes one or a plurality of first extension parts. The first extension part includes a first magnetic layer, a first counter magnetic layer, and a first nonmagnetic layer. The first magnetic layer includes a first portion, a first counter portion, and a first middle portion. A direction from the first portion toward the first counter portion is along the first direction. The first middle portion is between the first portion and the first counter portion. The first nonmagnetic layer is between the first counter magnetic layer and at least a portion of the first middle portion.

    摘要： A radiofrequency detection and acquisition system, which is based on SQUID and configured to be integrated into a nuclear magnetic resonance system, comprises a primary detection antenna, a flux transformer having an inlet winding connected to the primary detection antenna, a low critical temperature SQUID device for capturing the magnetic flux produced by an outlet winding of the flux transformer and supplying a secondary detection signal, a cryogenic device for cooling the SQUID device and the flux transformer, and means for processing the secondary detection signal emitted by the SQUID device to supply an analogue acquisition signal. The primary detection antenna may be of the volume type, comprising Helmholtz coils or saddle coils, or a more complex volume geometry, particularly gradiometric geometry. The means for processing the secondary detection signal may comprise a flux-locked loop, provided to linearize the response of the SQUID device.
