Abstract
We have studied the strong hole self-doping into LaMnO3(LMO) thin films produced by metal organic decomposition (MOD) method. With different heat treatment conditions, LMO thin films have been prepared by the MOD method in the 100 % O2gas atmosphere. We consider that the excess of O2-ions in LMO thin films induces the strong hole self-doping into LMO ones. The quantity of excess O2-ions in LMO is sensitive to the heat treatment conditions of the LMO production, especially the temperature, time and atmosphere gas. Although LMO single crystal is an antiferromagnetic insulator, LMO thin films we have produced in the 100 % O2gas atmosphere by use of the MOD method shows the properties of ferromagnetic metal.
