Abstract : The relationship of the magnetic anisotropy to the ion locations has been investigated in hexagona 6 L type crystals. The compositions studied were RbCo2Ni8-yCayF3 where both Co and Ca have a preference for 2a sites. The data show there are differences of the Co2+ ion anisotropy on the two sites 2a and 4f with a stong positive K2 for ions on the less symmetric 4f site. For certain compositions cones of easy magnetization from about the hexagonal c-axis which are found to have equilibrium positions that are sensitive to the applied magnetic field.
