Growth of oriented, single phase La1xCaxMnO3 thin films by physical vapor codeposition Academic Article uri icon

abstract

  • La1-xCaxMnO3 thin films with varying compositions (0.65 > x > 0.20) have been grown by codeposition of La, Ca and Mn onto single crystal LaAlO3 substrates heated to about 600C in 10-5 Torr of oxygen. Post-deposition anneals of the films at about 900C in pure flowing oxygen improve the magnetoresistive behavior of the films which show changes of resistance characteristic of colossal magnetoresistance between fields of 5 T and 0 with temperatures for the resistance peeks near room temperature. The annealed films have been characterized by resistance, magnetoresistance and thermopower measurements. 1998 Elsevier Science B.V. All rights reserved.
