Abstract

The de Haas-van Alphen (dHvA) effect and the ac susceptibility of CeP have been studied in the magnetic phases I and II for magnetic fields up to 16 T in the (010) and (110) planes. The magnetic transition field H1 between the phases I and II and the dHvA oscillations show an anomalous dependence on the magnetic-field history of the sample. The transition field H1 is 4.6 T (H∥[OO1]) in a virgin sample after zero-field cooling, while it shifts to 5.0 T after a few field sweeps between O and 14 T. The number of the fundamental components, and the frequencies and amplitudes of the dHvA oscillations depend strongly on the strength of the field applied prior to the measurements. We explain these anomalous hysteresis by assuming that there exist more than one magnetic phase in the phase-II region. Two and four dHvA branches are found in phases I and II, respectively. Their origins are discussed in comparison with the Fermi surface of LaSb. The branch α1 attributed to an electron surface shows good agreement with the angle dependence of the frequency determined from the period of the successive metamagnetic transitions above 20 T.
