DEMONSTRATION OF CANTILEVER MAGNETOMETRY IN PULSED MAGNETIC-FIELDS

The technique of cantilever magnetometry has been extended to pulsed m agnetic fields. Using micromachined single-crystal silicon cantilevers and capacitance detection, a utilizable sensitivity of similar to 10( -12) Am-2 in fields up to 36 T has been achieved. Mechanical resonance studies and torque magnetization measurements on a microcrystal of YB a2Cu3O7 demonstrate the feasibility of the technique in ''long pulse'' magnets. Prospects for short pulse magnets are discussed. (C) 1998 El sevier Science B.V. All rights reserved.
