摘要： A method and device for field detection are provided, in which one or more gradiometers (31, 32, 33) are positioned in the field and rotated about their axes. Rotation of a single gradiometer allows an output signal of the gradiometer to be analysed in the Fourier domain, which allows particular field components to be obtained, and also separates the field signal from noise, in the frequency domain. Use of three such rotating gradiometers with non-parallel axes allows a complete magnetic field gradient tensor to be obtained with data redundancy, and can reduce crosstalk.

摘要： A cryogenic apparatus for microscopy of physical properties of an object including a thin, stiff, transparent substrate or window (28) within the outer wall of the vacuum space (18) of a dewar and a cryogenic sensor (72) within the vacuum space and spaced very close distances to the window (28). This construction allows for positioning a sample for measurement outside of the vacuum space, at room temperature or higher and for microscopy of physical properties of the sample (91) by monitoring the output from the cryogenic sensor as it is scanned along the surface of the sample (91).

摘要： The invention concerns a SQUID magnetometer comprising: a SQUID (10); means (61) for applying a predetermined bias current to said SQUID (10); means (57, 62) for detecting an output of said SQUID (10) to which said bias current is being applied; feedback means (65) for feeding the output of said SQUID (10) back to an amount of the bias current to said SQUID (10); means (64) for applying a bias magnetic field to said feedback means (65); and controls means (40) for automatically adjusting said bias magnetic field in a state that said bias current is adjusted such that an output voltage of said SQUID is at its maximum when an initial working point of said SQUID is adjusted

摘要： The present invention provides an improved and simplified voltage step-up circuit (2) for a SQUID magnetometric sensor (1), which provides step-up of a voltage signal generated by a SQUID element (11). The SQUID element is exited by a modulated signal using the FLL method. In an example, a step-up means (22) comprises only one step-up transformer (22T) working at room temperature and an electronic amplifier (22A). The voltage signal is first stepped up by the transformer. A signal processing means (23) processes the stepped up signal with the modulation signal to output a magnetic field measurement signal (Vϕ). In another example, a bias current source (21) is also connected to terminals between SQUID element (11) and the transformer (22). A series resistor is connected between the transformer and one of the terminals. This allows a reduction in the number of terminals between the SQUID sensor (1) and the circuit (2).

摘要： Device for coupling an rf-SQUID to a super conducting tank circuit and a base plate, in which the tank circuit and the rf-SQUID form a coplanar structure, and the tank circuit has a slit. The base plate (10) is configured as an outer loop (10a) which is coplanar to the rf-SQUID (2) and to the tank circuit (1), and has a slit (11). The tank circuit (1) encircles an inner loop (1a), in which the slit (4) is embodied. The orientation of the slits (4; 11) of the inner loop (1a) and the outer loop (10a) to one another determines the resonance frequency fr.

摘要： This magnetic sensor comprises a flux transformer 2 having a superconducting thin film 2f formed on a sapphire substrate 2s, and a SQUID 1 disposed on the flux transformer 2 opposite thereto. In this magnetic sensor, since the sapphire substrate 2s, which can be obtained in a large size, is used for the flux transformer 2, even when the SQUID 1 is made smaller, the magnetic flux introduced from the flux transformer 2 into the SQUID 1 can be enhanced so as to increase the effective magnetic flux capturing area, whereby the detecting performance is improved, while the manufacturing cost can be reduced due to the smaller size of the SQUID 1.
摘要翻译： 该磁传感器包括具有形成在蓝宝石衬底2s上的超导薄膜2f的磁通变换器2和与其相对的磁通变压器2上的SQUID 1。 在该磁传感器中，由于可以将大尺寸的蓝宝石基板2s用于磁通变压器2，所以即使使SQUID 1变小，从磁通变换器2导入SQUID 1的磁通量 可以增强有效磁通捕获面积，从而提高检测性能，同时由于SQUID 1的尺寸较小，可以降低制造成本。
