17. Without detailed atomic parameters for the Ga-salts, these numbers are actually calculated for the homologous Fe-salts. However, with the very similar structure between the Ga- and Fe-salts for both λ- and κ-type, the discussions on the HI are not considered to be affected.

19. With a limited amount of the sample available and also with significant cancellation of the paramagnetism of the π-electrons by the core diamagnetism, we did not make any reliable direct measurements of χ(T) of our sample.
