Resumen
The low temperature magnetic properties of the Li2CuO2 compound have been investigated by
means of superconducting quantum interference device magnetometry. We find in addition to an
antiferromagnetic phase below 9.5 K a ferromagnetic-like steep rise of the magnetization around 2.8
K. The observed low temperature behavior is discussed by considering second and fourth order
magnetocrystalline ...

The low temperature magnetic properties of the Li2CuO2 compound have been investigated by
means of superconducting quantum interference device magnetometry. We find in addition to an
antiferromagnetic phase below 9.5 K a ferromagnetic-like steep rise of the magnetization around 2.8
K. The observed low temperature behavior is discussed by considering second and fourth order
magnetocrystalline effective anisotropy coefficients, in addition to the exchange couplings reported
in the literature. [--]
