In the first part of the paper the crystalline anisotropy of a number of hexagonal oxidic compounds containing barium is discussed. In the absence of an external magnetic field the magnetization vector can point in an arbitrary direction with respect to the c-axis. This behaviour can already be described with two anisotropy constants. Examples are given of materials with a preferential direction (along the c-axis), with a preferential plane (basal plane) as well as with a preferential cone for the magnetization vector. The latter case occurs at relatively low temperatures in crystals containing cobalt. There are also materials in which, at different temperatures, all three types of anisotropy occur. The relatively weak anisotropy in the bas...
