Show affiliationsThe importance of determinations of the gyromagnetic effect is discussed in relation to paramagnetism, though the gyromagnetic amplitude is so minute as to render accurate determination difficult in some cases. (i) In the case of ferromagnetism the value of g eq, falling dots 2 found experimentally is in accord with theory. (ii) In the case of paramagnetic substances only one accurate determination has yet been made, namely that for Dy+++: it gives g = 4/3, in good agreement with both susceptibility measurements and theory. Preliminary data on Mn++ and Cr+++ suggest, in agreement with susceptibility results, that both these ions are in S-states. (iii) Experiments in progress on Eu+++ taken in conjunction with the Van Vleck theory should yield useful information.
