We propose to study the spin-density distribution and to determine the precise crystal structure in ferromagnetic SrRuO3. SrRuO3 is the only simple ruthenate that exhibits ferromagnetic order at ambient conditions. A study of the spin-density distribution in SrRuO3 appears highly interesting in view of the general importance of ferromagnetism in ruthenates, and in view of the proposed half metallic behavior of SrRuO3.
