Abstract
A study of the magnetization of the antiferromagnetic magnetoelectric cryst al LiCoPO4 as a function of temperature and the strength of a magnetic fiel d oriented along the antiferromagnetic vector reveals features due to the p resence of a weak ferromagnetic moment. The value of the magnetic moment al ong the b axis at 15 K is approximately 0.12 G. The existence of a ferromag netic moment can account for the anomalous behavior of the magnetoelectric effect observed previously in this crystal. (C) 2001 American Institute of Physics.
