摘要：

Neutron diffraction experiments on CrAs revealed that the pressure versus temperature phase diagram and magnetic structures in the phase diagram are very similar to those of CeP. The difference is critical pressure values P-c, which are about 0.3 GPa in CeP and about 1.2 GPa in CeAs, and above which the long period magnetic structures composed of Gamma(7) and Gamma(8) Ce (0 0 1) planes appear. This is discussed in connection with the difference of their carrier numbers and the Gamma(8) P-f mixing effect. (C) 2000 Published by Elsevier Science B.V. All rights reserved.
