"Weak itinerant ferromagnetism in YCo₉Si₄*";
Physica B: Condensed Matter, 359-361 (2005), S. 1177 - 1179.

Weak itinerant ferromagnetism in YCo9Si4 below about 25K is studied by means of magnetisation, specific heat, and resistivity measurements. Single-crystal X-ray refinements at room temperature reveal a fully ordered distribution of Y, Co and Si atoms within the tetragonal space group I4/mcm isostructural with LaCo9Si4: The latter exhibits itinerant electron metamagnetism with an induced moment of about 1mB=f :u: above 6 T, whereas YCo9Si4 exhibits a spontaneous magnetisation M0 ` 12Am2=kg at 2K which corresponds to an ordered moment of about 1:6mB=f :u: indicating weak itinerant ferromagnetism.
