Abstract

We report on time-resolved pump-probe measurements of spin-dependent dynamics in strained Nd _0.67Sr _0.33MnO ₃ thin films grown on three different substrates: LaAlO ₃ (001), SrTiO ₃ (001), and NdGaO ₃ (110). The temperature dependence of the long-lived spin-relaxation component is represented well by a power-law decay of long-range correlations, clearly showing the transition from quasilong-range ferromagnetic order to a disordered paramagnetic phase. The "disordering" temperature, T _M, where the intermediate phase of quasilong-range order appears, varies according to the creation of static-distortion waves under different strain forces.
