“…CeAl 2 orders antiferromagnetically at T N = 3.8 K, and the dHvA measurements are made at B > B c = 5.27 T in a high-field phase above the metamagnetic transition [29,46]. These measurements demonstrated striking similarity between the Fermi surfaces in CeAl 2 and sister compound LaAl 2 , although the moderately heavy masses of ≈ 15m 0 were registered at least for two electron sheets.…”

The theory describing the electron mass enhancement in Kondo-lattice heavyfermion systems is presented. The description is based on the picture of a spin Fermi liquid of RVB type which strongly interacts with conduction electrons. It is shown that the electronspinon scattering results in large phase shifts for conduction electrons near the Fermi level which mimic the resonance renormalization but does not involve f-electron states. The results are compared with dHvA data for several Ce-based compounds.

“…The antiferromagnetic spin alignment can be understood in terms of nesting features of the underlying Fermi surface of LaAl2 and is not caused by the 4/ states. Nesting features were observed along [111] and [110]. Please note that the spins in successive (111) planes are aligned antiparallel and the modulation is along [110].…”
