Electromagnetic and microwave absorption performance of some transition metal doped La0.7Sr0.3Mn1−xTMxO3±δ(TM = Fe, Co or Ni)
Shuyuan Zhang, Quanxi Cao
► The perovskite phase of La0.7Sr0.3Mn1−x(Fe, Co or Ni)xO3±δ(x=0, 0.2) was formed. ► La0.7Sr0.3Mn1−xTMxO3±δ(TM=Fe, Co or Ni,x=0, 0.2) had negative susceptibility. ► The electromagnetic loss has been greatly enhanced after TM (Fe, Co or Ni) doping. ► The absorbing peak moved to the lower frequency after TM (TM=Fe, Co or Ni) doping. ► The microwave absorption property was improved after TM (TM=Fe, Co or Ni) doping.
