Abstract

Phase separated perovskite manganites have competing phases with different crystal structures, magnetic and electronic properties. Hence, strain effects play a critical role in determining the magnetic properties of manganite thin films. Here we report the effect of anisotropic stress on the magnetic properties of the phase separated manganite (La $_{0.4}$ Pr $_{0.6}$ ) $_{0.67}$ Ca $_{0.33}$ MnO $_{3}$ . Thin films of (La $_{0.4}$ Pr $_{0.6}$ ) $_{0.67}$ Ca $_{0.33}$ MnO $_{3}$ grown under anisotropic in-plane stress on (110) NdGaO $_{3}$ substrates display in-plane mangetic anisotropy and single domain to multidomain transition as a function of temperature. Angle dependent magnetization measurements also show that the magnetization reversal occurs mainly through the nucleation $&$ propagation mechanism. By comparing the results with (La $_{0.4}$ Pr $_{0.6}$ ) $_{0.67}$ Ca $_{0.33}$ MnO $_{3}$ thin films grown on (001) SrLaGaO $_{4}$ substrates, we have confirmed that the magnetic anisotropy is mainly due to substrate induced anisotropic stress. Our results suggest novel avenues for storing magnetic information in nanoscale magnetic media.
