Ferromagnetic bubble clusters in Y0.67Ca0.33MnO3 thin films
We studied the ferromagnetic topology in a Y0.67Ca0.33MnO3 thin film with a combination of magnetic force microscopy and magnetization measurements.

| Sumario: | We studied the ferromagnetic topology in a Y0.67Ca0.33MnO3 thin film with a combination of magnetic force microscopy and magnetization measurements. Our results show that the spin-glass like behavior, reported previously for this system, could be attributed to frustrated interfaces of the ferromagnetic clusters embedded in a non-ferromagnetic matrix. We found temperature dependent changes of the magnetic topology at low temperatures, which suggests a non-static Mn3+/Mn4+ ratio. |
