Torque signals from a metal single crystal in a rotating magnetic field and the corresponding angular position of the rotating magnet, for both directions of rotation, were digitally recorded on magnetic tape at equal time intervals, with a maximum recording frequency of 18.8 data pairs per degree of rotation. The signals included induced, background, and de Haas–van Alphen effect torques. Only the induced torque is an odd function of rotation direction, and enhancement of the induced torque signals is achieved by subtracting the data obtained for one rotation direction from that for the other rotation direction. Computer analysis of recorded data yielded enhancement only if prior correction of each angular reading was performed to take into account the finite compliance of the torque magnetometer. The resulting enhanced rotation diagrams were plotted on a Calcomp plotter. The technique is also useful for continuous recording of anisotropy torque data from weakly magnetic samples, since the induced‐torque signals can be cancelled by adding the data from one rotation direction to those obtained from the other direction.
