We have investigated complete anisotropy in the magnetic properties of the charge transfer salt $\beta $-(BDA-TTP) 2FeCl 4 [BDA-TTP = 2,5-bis(1,3-dithian-2-ylidene)-1,3,4,6-tetrathiapentalene] and revealed that the anisotropy in both the temperature and the field dependences of magnetization below TN show behaviours different from those for typical antiferromagnets. Key words. Antiferromagnet - anisotropy - Smagnetization.
