Abstract (EN):
Aerosol-assisted MOCVD was used to grow simultaneously thin films of La-Ca-MnO3 system on MgO(100) and LaAlO3(100) substrates. The films deposited on LaAlO3 have better structural quality, and higher magnetization. In films with Mn excess T-c can be enhanced, upon oxygen annealing, up to almost the room temperature. The annealing degrades the magnetic properties of the films deposited on MgO substrates.
