摘要：
In recent years, all-manganites superlattices have revealed enhanced properties, making them promising for new technological devices. Therefore, we studied the magnetotransport properties of epitaxial [La0.7Sr0.3MnO3/Nd0.6Ca0.4MnO3](x10) (LSMO/NCMO) superlattices with different NCMO thickness. We addressed the magnetoresistive (MR) behavior at different temperatures, using pulsed magnetic fields up to 25 T. The field-dependent MR curves were then analyzed using a modified hopping conduction model, allowing us to estimate the spin moment value (J) associated with the formation of magnetic clusters in our samples.
