Neutron diffraction study and magnetic properties of La(1-x)Ba(x)CoO(3) (x = 0.2 and 0.3).

The magnetic properties together with the crystal and magnetic structures of the cobaltites La(1-x)Ba(x)CoO(3) (for x = 0.2 and 0.3) are determined by DC magnetization, AC magnetic susceptibility and neutron powder diffraction measurements over a broad spectrum of temperatures.
