摘要

In this work, we present a novel hybrid magnetic sensor that combines the unique properties of manganite and graphene to measure both the magnitude and direction of a magnetic field. The sensor consists of a nanostructured manganite film to detect the magnetic field strength and a graphene layer to determine the angle between the magnetic field and the sensor plane. This dual sensor approach increases sensitivity over a wide range of magnetic field strengths and provides directional information, making it ideal for applications such as object positioning and navigation. The sensor design, based on a voltage divider configuration, has been optimized to achieve high sensitivity. Experimental results in pulsed magnetic fields up to 21 T demonstrated the increased sensitivity offered by the graphene-manganite combination. In addition, a measurement system for recording and processing data was developed that enables real-time measurement of the magnetic field magnitude and its orientation.
