Synthesis of Fe3Se4 Nanoplates with Room-Temperature Ferrimagnetism
Fe-based two-dimensional (2D) materials have attracted considerable attention as an optimal platform for exploring magnetism, superconductivity, and phase transitions. In this study, we successfully fabricated Fe3Se4 nanoplates on WSe2 nanosheets via a chemical vapor deposition approach. Optical microscopy images disclose that Fe3Se4 nanoplates either display single domains or achieve complete coverage on the WSe2 nanosheets. Magneto-transport measurements exhibit a captivating crossover of magnetoresistance (MR) with feeble hysteresis around 120 K, where positive and negative MR values are respectively witnessed below and above this temperature. This phenomenon is ascribed to the alterations in the dominant spin characteristics. Another salient feature is the intersection of hysteresis branches observed in the anomalous Hall effect measurements. Moreover, both the magneto-transport and vibrating sample magnetometer outcomes suggest that Fe3Se4 nanoplates possess magnetic properties near room temperature. These findings imply that Fe3Se4 nanoplates are prospective candidates for the development of energy-efficient logic devices.
