Abstract

904,521. Magnetic testing apparatus. COMMISSARIAT A L'ENERGIE ATOMIQUE. Dec. 29, 1958 [Dec. 30, 1957], No. 41913/58. Class 37. In a magnetometer of the type using Hall effect in a semi-conductor, the voltage across the output electrodes of the semi-conductor crystal is compared with a voltage at the slider of a directly-calibrated potentiometer fed with a current proportional to that flowing through the feed electrodes of the crystal. In Fig. 3, the potentiometer, calibrated in Gauss and crystal 21 are fed in parallel from the source 27. Resistor R5 is first adjusted so that the galvanometer 40 reads zero when switch 37 is open. The switch is then closed and the potentiometer 34 adjusted for balance. Temperature errors in crystals having a negative temperature coefficient of resistance are minimized by using resistors R1, R2 having high values compared with the crystal 21. Temperature compensation may also be achieved by means of a resistor 39 having negative temperature coefficient and mounted in contact with the crystal. Hall effect crystals specified may be of germanium, silicon, indium antimonide or indium arsenide.
