Abstract

Current-processing–induced anisotropic conduction (CIAC) has been observed recently in La_1−xCa_xMnO₃ (x= 0.2, 0.33) films. Here we report a more applicable and simple method, applying processing current at room temperature, to produce such anisotropic conduction. Using this method, we have examined La_1−xCa_xMnO₃ (x= 0.2, 0.33), La_0.67Sr_0.33MnO₃, Pr_0.7Ca_0.3MnO₃, La_0.35Pr_0.32Ca_0.33MnO₃ and La_0.7Ce_0.3MnO₃ films grown on SrTiO₃ substrates, and found CIAC in all these films, showing CIAC is a fairly universal phenomenon for manganites. The method exhibits good ability to process samples of large resistance/size. We even got remarkable anisotropic conduction in a manganite film as long as 3 mm. Our effort provides a very simple method to prepare such samples, which will help to further researches in this field.
