Abstract

We report the temperature dependence of the magnetic anisotropy in both compressive and tensile strained films of Pr_0.67Sr_0.33MnO₃ (PSMO). Compressive strain induced by growth on LaAlO₃ (LAO) substrates results in a spontaneous out-of-plane magnetization, while tensile strain (grown on SrTiO₃) results in in-plane magnetization. The coefficient of linear proportionality between the magnetic anisotropy energy and the tetragonal strain for both compressive and tensile strained PSMO films is larger than that found previously in strained La_0.67Ca_0.33MnO₃ films. From the data, we estimate a 20 unit cell magnetic domain wall width for PSMO / LAO. Scattering from such a narrow domain wall could produce a potentially significant contribution to the resistivity.
