Pressure effect on magnetoresistance of CeSb2

Temperature and field-dependent electrical resistance of CeSb2, has been measured at high pressure. The Curie temperature and the metamagnetic transition field are enhanced by pressure until they become unobservable in R(T) and R(H) curves at 2.1 GPa. There is pressure-induced large hysteresis behavior in R(T) which could have crystallographic origin. (C) 2000 Elsevier Science B.V. All rights reserved.
