Abstract
It is shown that, for a paramagnetic Fermi liquid, the temperature dependence of the magnetic susceptibility, χ( T), at low temperatures is given by χ(T) = χ(0) − bT 2 ln(T/T∗) , where b and T ∗ are constants. This relation predicts that the susceptibility should exhibit a maximum at temperature T max = T ∗ /√e ≈ 0.61T ∗ . arise from the Fermi liquid effect, i.e. the effect of interactions between quasiparticles with a Fermi type spectrum. The susceptibility maximum predicted in the above formula has been observed universally in various groups of substances such as 4d- and 5d transition metals, Laves phase compounds and heavy fermion compounds.
