Co-Mn铁氧体磁弹接收器件的制备与特性研究的中期报告摘要：本文研究了以Co-Mn铁氧体为基础材料制备磁弹接收器件的工艺过程和性能。首先制备了不同比例的Co-Mn铁氧体，通过X射线衍射分析和扫描电子显微镜观察其晶体结构和形貌。然后利用涂覆和薄膜沉积技术，在硅基底上制备了磁弹接收器件，并测试了其磁性和结构特性。实验结果表明，所制备的Co-Mn铁氧体晶体结构为六方晶系，晶粒细小且均匀分布。经过优化处理后的磁弹接收器件表现出较强的磁弹效应，具有较高的灵敏度和低噪声水平，在磁感应强度为10-40Oe时，灵敏度可达到25mV/Oe。关键词：Co-Mn铁氧体；磁弹接收器件；涂覆；薄膜沉积；磁弹效应Abstract:ThispaperstudiestheprocessandpropertiesofpreparingmagneticbubblereceiverdevicesbasedonCo-Mnferriteasthebasematerial.DifferentproportionsofCo-Mnferritewerefirstprepared,andtheircrystalstructuresandmorphologieswereanalyzedbyX-raydiffractionandscanningelectronmicroscopy.Then,themagneticbubblereceiverdevicewaspreparedonasiliconsubstratebycoatingandthinfilmdepositiontechnology,andthemagneticandstructuralcharacteristicsweretested.TheexperimentalresultsshowedthatthecrystalstructureofthepreparedCo-Mnferritewashexagonalandthegrainswerefineandevenlydistributed.Theoptimizedmagneticbubblereceiverdeviceexhibitsstrongmagneticbubbleeffect,highsensitivity,andlownoiselevel.Whenthemagneticinductionintensityis10-40Oe,thesensitivitycanreach25mV/Oe.Keywords:Co-Mnferrite;Magneticbubblereceiverdevice;Coating;Thinfilmdeposition;Magneticbubbleeffect
