Original Kurzfassung:
A spin?sensitive linear response theory is presented that includes correlations beyond the well?known random phase approximation. Especially for very dilute systems, such correlations play an important role. The response functions obtained give insight into both charge and longitudinal magnetic excitations. In addition to the spin?plasmon, we propose a new regime where no magnetic excitation is possible, namely the magnetic anti?resonance. Both effects lie in experimentally accessible ranges.
