  • Chemical vapor deposition method of growing oxide films with giant magnetoresistance
    Patent number: 5487356
    Abstract: A chemical vapor deposition method for forming films or coatings of metal oxide films showing a giant magnetoresistive effect, with the metal oxides having the formula La.sub.x A.sub.1-x MnO.sub.3 wherein A is selected from the group consisting of barium, calcium, manganese, and strontium, and x is a number in the range of from 0.2 to 0.4. The method uses a liquid source delivery CVD approach, wherein source reagent solution precursor is flash vaporized and is delivered to a CVD chamber, wherein it decomposes to deposit the multicomponent metal oxide films with well-controlled stoichiometry.
