Abstract
We report the development of a piezoelectrically driven rotator for use in high magnetic fields at low temperatures. This rotator, controllable with t wo lead wires instead of a driving shaft, is designed to fit into a narrow sample space with a diameter of 13 mm and is capable of making rotations wi th a high angular resolution of similar to0.01 degrees in magnetic fields r eaching 33 T. In addition, estimated heat dissipation of less than 100 muW accompanied by rotation allows continuous rotations in a dilution refrigera tor (T < 100 mK). (C) 2001 American Institute of Physics.
