EFFECT OF MICRO-NANOFABRICATION TECHNOLOGIES IN La_(2/3)Ca_(1/3)MnO_3 THIN FILMS

La2/3Ca1/3MnO3(LCMO) and YBa2Cu3O7(YBCO,The superconducting material is the key point of the superconducting electrical power technology.) are the same type materials of the strongly correlated systems.This LCMO material belongs to the doped perovskite oxides of the type R1-xAxMnO3(R=La,Nd,etc.,a trivalent rare earth element and A=Ca,Sr,etc.,a divalent element).Formerly,the colossal magnetoresistance(CMR) have attracted great interest in these materials.In order to investigate the origin of this mechanism,vast research has been studied. However,whether the characteristics of this LCMO material can be changed if it was modified by some special method? The LCMO thin films were modified by using Micro-nanofabrication technologies.We present in this article the investigation on the result.
