In order to investigate the magnetic state around hole density 1/8 in LaSr-214, {mu}SR experiments were carried out for the samples of Zn-free La{sub 2{minus}x}Sr{sub x}CuO{sub 4} and Zn-doped La{sub 2{minus}x}Sr{sub x}Cu{sub 1{minus}y}Zn{sub y}O{sub 4}. For Zn-free samples, {mu}-spin rotation was observed in x = 0.115 below about T{sub r} = 10K, implying magnetic order, but not observed in x = 0.125. On the other hand, Zn-doping brought about {mu}-spin rotation in x = 0.125 sample below T{sub r} = 7K, implying growth of magnetic order but decreased T{sub r} in x = 0.115, meaning destruction of magnetic order. This indicates that Zn-doping pins dynamical spin modulation, resulting in static magnetic order in x-0.125 sample.
