Abstract
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 w ith Mn excess T-c can be enhanced, upon oxygen annealing, up to almost the room temperature. The annealing degrades the magnetic properties of the fil ms deposited on MgO substrates. (C) 1999 Elsevier Science B.V. All rights r eserved.
