Studies of unusual magnetic and electronic properties of the low-carrier system CeP by synchrotron X-rays

摘要

We have observed superlattice reflections from the low-carrier system CeP under high pressures up to 2 GPa and also under magnetic field up to 12.5 T by means of synchrotron X-ray diffraction. The observed intensities of superlattice reflections are well explained by a model that takes into account both the lattice and charge modulation due to the periodic arrangement of ferromagnetic double layers of Gamma(8)-like Cc ions in the lattice of Gamma(7) Cc ions. A new magnetic phase with the period of nine Cc planes was found in the experiment at the magnetic field of 12.5 T. (C) 2003 Elsevier B.V. All rights reserved. [References: 9]
