Abstract
The M-T curves,ESR curves,p-T curves and MR-T curves of La_(0.67-x)Sm_xSr_(0.33)MnO_3(x=0, 0.10,0.20,0.30)were measured.The experimental results indicate that,with the increase of Sm doping, the system undergoes a transition from long range ferromagnetic order to the cluster-spin glass state and further to antiferroinagnetic order.The variation in magnetic structure and extra magnetic coupling caused by Sm doping led to colossal magnetoresistance.
