Zn and Ni doping effects on the low-energy spin excitations in LaSrCuO
M. Kofu, H. Kimura, K. Hirota
Impurity effects of Zn and Ni on the low-energy spin excitations were systematically studied in optimally doped La1.85Sr0.15Cu1-yAyO4 (A=Zn, Ni) by neutron scattering. Impurity-fre…

Novel in-gap spin state in Zn-doped La_1.85Sr_0.15CuO_4
H. Kimura, M. Kofu, Y. Matsumoto +1
Low-energy spin excitations of La1.85Sr0.15Cu1-yZnyO4 were studied by neutron scattering. In y=0.004, the incommensurate magnetic peaks show a well defined ``spin gap'' below Tc. T…
