The ternary compound LaFe4P12 having a ’’filled skutterudite’’ structure is a superconductor with Tc = 4.08 K. We have used the Mossbauer effect of 57Fe to show that the magnetic moment of Fe in LaFe4P12 is less than 0.01μB. The value of the measured isomer shift indicates a spin‐paired 3d configuration of Fe. The temperature dependence of the shift and the resonance fraction are used to establish a weak coupling of 3d electrons with the phonons, the coupling parameter being about 0.4 to 0.5.
