Abstract
The magnetic anisotropy, Δχ, of the smectic A phases of two series of lanthanide complexes derived from Schiff 's bases and C12H25OSO3 or NO3 anions is measured. The Δχ values of some of the lanthanide (Tb, Dy, Ho) complexes are about two orders of magnitude greater than those of usual liquid crystals. Experimental data are interpreted within the framework of Bleaney's theory of the anisotropic paramagnetic susceptibility. It is shown that the sequence of Δχ signs and the tendency to variation of their magnitudes through the lanthanide series are in accordance with theoretical predictions for isostructural series of lanthanides.
