Novel Dynamical Effects and Persistent Memory in Phase Separated Manganites
Novel Dynamical Effects and Persistent Memory in Phase Separated Manganites
The time dependent response of the magnetic and transport properties of Fe-doped phase separated (PS) manganite ${\mathrm{L}\mathrm{a}}_{0.5}{\mathrm{C}\mathrm{a}}_{0.5}{\mathrm{M}\mathrm{n}\mathrm{O}}_{3}$ is reported. The nontrivial coexistence of ferromagnetic (FM) and non-FM regions induces a slow dynamics which leads to time relaxation and cooling rate dependence within the PS regime. This dynamics influences physical properties …
