We investigate the structural variation and physical properties of layered La2M_5As3O2(M=Cu,Ni)compound upon Co doping.It is found that the substitution of Co ion just induces the monotonous change of lattice constants wit
In order to counteract the demagnetization caused by eddy current loss,widespread attention has been devoted to increasing the resistivity of permanent magnets.We prepared 2:17-type Sm Co magnets doped with different ZrO2contents and investigat
