Notes:
A technique has been devised for precise in situ sample angular positioning and readout in a commercial superconducting quantum interference device (SQUID) susceptometer. The axis of rotation is perpendicular to the applied magnetic field and the temperature range is from 2 K up to room temperature. The technique has an accuracy in angular position of about 0.3%, approximately one degree over one complete rotation. A small coil with an ac current excitation is fixed on the sample stage, and the ac SQUID response is used to determine the angular position of the stage. © 1998 American Institute of Physics.
