Abstract
The low temperature magnetic properties of the Li2CuO2 compound have been i nvestigated by means of superconducting quantum interference device magneto metry, We find in addition to an antiferromagnetic phase below 9.5 K a ferr omagnetic-like steep rise of the magnetization around 2.8 K. The observed l ow temperature behavior is discussed by considering second and fourth order magnetocrystalline effective anisotropy coefficients, in addition to the e xchange couplings reported in the literature.
