Abstract

759,047. Semi-conductor devices. SIEMENSSCHUCKERTWERKE AKT.-GES. Nov. 12, 1953 [Nov. 12, 1952], No. 31411/53. Class 37. An instrument for measuring a magnetic field comprises a member, consisting of a semi-conducting compound of Am Bv type and having a carrier mobility of at least 6000 cms.<SP>2</SP>/volt. sec. AIII Bv type refers to a compound of one of the elements B, A1, Ga, or In with one of the elements N, P, As or Sb. The field may be measured by means of a bridge circuit adapted to measure the change in resistance of the member when subjected to the magnetic field. Alternatively the Hall effect of the member may be utilized as shown in Fig. 2, in which measurement is effected by balancing the Hall potential developed in member M against a standard potential obtained from potentiometer K. Fig. 3 shows a bridge circuit arrangement in which the combination of the resistance change and the Hall potential both developed by member M, when it is subjected to the magnetic field, are utilized to measure the magnetic field. Specification 719,873 is referred to.
