Abstract
We have investigated the magnetic moment of the W ion in the ferrimagnetic double perovskites and by x-ray magnetic circular dichroism at the W edges. In both compounds a finite negative spin and positive orbital magnetic moment was detected. The experimental results are in good agreement with band-structure calculations for using the full-potential linear muffin-tin orbital method. It is remarkable that the magnetic ordering temperature, , is correlated with the magnetic moment at the “nonmagnetic” W atom.
