Integrated optically pumped magnetometer for measurements within Earth's magnetic field
G. Oelsner, R. IJsselsteijn, T. Scholtes +7
We present a portable optically pumped magnetometer instrument for ultra-sensitive measurements within the Earth's magnetic field. The central part of the system is a sensor head o…
Performance analysis of an optically pumped magnetometer in Earth's magnetic field
G. Oelsner, V. Schultze, R. IJsselsteijn +1
We experimentally investigate the influence of the orientation of optically pumped magnetometers in Earth's magnetic field. We focus our analysis to an operational mode that promis…
Sources of heading error in optically pumped magnetometers operated at Earth's magnetic field
G. Oelsner, V. Schultze, R. IJsselsteijn +2
When optically pumped magnetometers are aimed for the use in Earth's magnetic field, the orientation of the sensor to the field direction is of special importance to achieve accura…
Voltage-current and voltage-flux characteristics of asymmetric high TC DC SQUIDs
I. L. Novikov, Ya. S. Greenberg, V. Schultze +2
We report measurements of transfer functions and flux shifts of 20 on-chip high T DC SQUIDs half of which were made purposely geometrically asymmetric. All of these SQUIDs were…
Anomalous Periodicity of the Current-Phase Relationship of Grain-Boundary Josephson Junctions in High-Tc Superconductors
E. Il'ichev, V. Zakosarenko, R. P. J. IJsselsteijn +5
The current-phase relation (CPR) for asymmetric 45 degree Josephson junctions between two d-wave superconductors has been predicted to exhibit an anomalous periodicity. We have use…
