| heal.abstract | Films deposited by pulsed laser ablation from La2/3Ca1/3MnO3 targets exhibit a large variety of properties depending on the exact preparation conditions. The as-deposited films at high enough oxygen pressures P-O2, have transition temperatures (T-c) close to that of the target material (265 K). At lower P-O2 the films can be made to have lower T-c's but as P-O2 is decreased below a certain value, an insulating behavior in all the temperature range is observed. X-ray diffraction pole-figure measurements of these insulating films indicate an extremely strained structure. By post annealing in oxygen these films are recrystallised and a T-c of 265 K is restored. However the highest magnetoresistance value of (rho(0)- rho(H))/rho (H)= 109000%, at H= 50 kOe, was obtained for a film having a transition temperature of 135 K. (C) 1998 Elsevier Science S.A.
