The paramagnetic spin fluctuations in Pd//2MnSn (localized spin system) and MnSi (weak itinerant ferromagnet) have been studied by polarized neutron scattering with polarization analysis over the wide energy, wave vector and temperature ranges. The results give an excellent agreement with the current theories (three pole approximation for Pd//2MnSn and MK-SCR theory for MnSi).
