Experimental evidence for magnetic dipole absorption of Ag particles, produced by solid state reaction in a KCl single crystal, is given for the first time. Absorption in the FIR better follows a ω 4 than ω 2 law. A maximum absorption at 65 cm −1 is up to five times as high as the absorption plateau in the MIR. Therefore the low temperature scattering rate of electrons is clearly lower than for electric dipole absorption. A quantitative comparison shows absorption still 10 to 50 times higher than predicted by current quantum mechanical theories.
