“…As with most metals, many of them undergo transitions, either to a magnetically ordered phase [l] or to a superconducting phase [2]. Except in rare cases [3], the magnetic ordering precludes further transitions to a superconducting phase. There is a small but important class of transition metals compounds and alloys that remain normal paramagnetic metals down to T = 0 K. In these systems, it is believed that the interaction responsible for magnetic ordering is just too feeble to produce a phase transition but strong enough to exhibit the precursor effects usually associated with a low-temperature phase transition [l, 2,4].…”

The oscillatory part of the thermodynamic potential and magnetization are calculated for a paramagnetic system that is near to a magnetic instability. The dominant excitations of such an exchange enhanced Fermi liquid are persistent spin fluctuations. The electrons are scattered by processes in which the spin fluctuations are emitted and absorbed. The electron spin fluctuation interaction results in a many-body resonance of the electronic density of states at the Fermi level. It is shown that the spin fluctuations manifest themselves in the de Haas-van Alphen oscillations. The amplitude of the oscillations is reduced, the reduction is dependent on the enhancement of the linear T term in the electronic specific heat. The results are applied to the experiments on CeSn, and on Pd.Fur ein paramagnetisches System in der Niihe einer magnetischen Instabilitat wird der oszillierende Anteil des thermodynamischen Potentials und der Magnetisierung berechnet. Die relevanten Anregungen sind durch Spinfluktuationen gegeben. Die Streuprozesse der Elektronen sind die Emission und die Absorption von Spinfluktuationen. Diese Spinfluktuationen resultieren in einer Amplitudenreduktion der de Haas-van Alphen-Oseillationen. Diese Amplitudenreduktion ist eine Funktion der Verstarkung des beziiglich der Temperatur linearen Teils der elektronischen spezifischen Wlrme. Die Resultate werden mit Experimenten an CeSn, und Pd verglichen.
