低维反铁磁材料实现“可读可写”——为新一代低功耗高速芯片开辟新路径
2026-06-10 · 系列介绍 · 百灵威授权转载
复旦大学物理学团队利用自主开发的多模态磁光显微技术,发现低维层间反铁磁体系能在磁场下实现确定性的双稳态整体切换,并完善了经典磁学理论。这一突破推动反铁磁材料从“有趣而无用”迈向“可读可写”,为开发新一代低功耗、高速运算芯片提供了新路径。相关成果发表于《自然》。我司提供系列高纯磁性金属有机前驱体(钴、镍、锰、铁等)、二维材料生长源及表征用衬底,助力低维反铁磁材料的可控合成与器件构筑。
产品优势及特点:
- - 磁性金属有机前驱体:提供二(乙基环戊二烯基)锰(II)、二(甲基环戊二烯基)镍(II)、双(环戊二烯)钴(II)等高纯度前驱体(≥99.99% metal basis),适用于MOCVD/ALD生长低维反铁磁薄膜(如CrS₂、MnS₂、NiTe₂等)。- - 二维材料生长源:含钼、钨、钛等前驱体,可用于构建异质结或调控磁各向异性。
- - 衬底与表面处理:提供晶圆级石墨烯转移膜、硅衬底、石英衬底等,以及等离子刻蚀预处理所需的湿电子化学品。
- - 器件制备配套:正胶显影液、负胶漂洗液、氟化液清洗剂等,支持光刻图案化与器件加工。
- - 表征辅助:高纯溶剂用于样品清洗,标准钢瓶用于前驱体安全输送,保障磁光显微等表征的样品质量。
应用场景:
- - 低维反铁磁材料(如过渡金属硫族化合物、卤化物)的MOCVD/ALD合成- - 二维磁性异质结与自旋电子器件制备
- - 反铁磁体磁化翻转机制研究(磁光克尔效应、磁畴成像)
- - 低功耗、高密度磁存储及逻辑器件开发
