摘要

在这项工作中，我们介绍了一种新型混合磁传感器，它结合了锰酸盐和石墨烯的独特特性，可以测量磁场的大小和方向。该传感器由纳米结构的锰酸盐薄膜和石墨烯层组成，前者用于检测磁场强度，后者用于确定磁场与传感器平面之间的角度。这种双传感器方法提高了在宽磁场强度范围内的灵敏度，并提供了方向信息，因此非常适合物体定位和导航等应用。基于分压器配置的传感器设计经过优化，可实现高灵敏度。在高达 21 T 的脉冲磁场中的实验结果表明，石墨烯-锰矿组合提高了灵敏度。此外，还开发了一个用于记录和处理数据的测量系统，能够实时测量磁场大小及其方向。

Hybrid manganite-graphene sensor for magnetic field magnitude and direction measurement.

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.
