A simple sample-inverting cryostat for Hall resistance measurements

A simple sample-inverting cryostat with no mechanical gears and motors has been introduced to a superconducting magnet up to 17 T combined with a variable temperature insert from 1.5 to 300 K for the Hall resistance measurements. An elliptical sample stage surrounded by a coil in 100 turns is turned upwards or downwards by switching the current to the coil under a magnetic field. The direction of the stage is controlled by the minimum current from 100 mA at 0.2 T to 1 mA at 15 T. (C) 2003 Elsevier Science B.V. All rights reserved.
