High-field magnetization measurements using the single-turn coil technique
not only give detailed information on the critical magnetic field of level
crossing anomalies in the rare-earth zircons TmPO4 and PrVO4, but also prov
ide strong evidence of hysteresis effects in up- and down-sweep of the exte
rnal magnetic field. (C) 2001 Elsevier Science B.V. All rights reserved.
