We have measured magnetization under high pressure of Yb 0.9Y0.1InCu4 which exhibits a valence transition at Tv=28K. With applying pressure, Tv is lowered. At P=1.6GPa, collapse of the valence transition and the occurrence of ferromagnetism are simultaneously observed. Considering the results of Yb0.8Y 0.2InCu4, both of the phenomena are definitely related. The Curie temperature of this ferromagnetism is estimated to be 2.3 K.
