Abstract
A gyrator for AC signals comprises a Hall effect material, means for coupling an alternating current (I; I) into the Hall effect material, means for permeating a Hall effect material with a magnetic field that is perpendicular to the plane or surface of the material, and means far converting a current (I; I), which was generated by the current Iperpendicularly to the electric field generated by Iin the Hall effect material, into an output voltage (U; U). A transformer is provided between at least one conductor loop () made of a normal-conducting or semi-conducting material and at least one conductor loop () made of the Hall effect material for coupling the current (I; I) into the Hall effect material and/or for converting the current (I; I) in the Hall effect material into the output voltage (U; U). It was found that eliminating an inefficient galvanic coupling of the Hall effect material to metallic or semi-conducting conductors minimizes the dissipative losses that occur during the conversion of the input current (I; I) into the output voltage (U; U). The gyrator can thus also be used for highly sensitive experiments in quantum information processing at low temperatures.
