摘要

二维(2D)磁性半导体由于其强大的二维量子效应、表面效应和自旋态控制的结合,在基于自旋的信息处理技术中至关重要。然而,大多数用于调谐二维磁体的实验方法在低温下获得纯铁磁性。本文提出了一种利用超临界CO2实现二维MoO3−x缺陷丰富的纳米结构的缺陷工程策略,并根据超临界压力的变化,通过引入Mo5+离子获得并调整其室温铁磁性。在缺陷区,五配位[Mo5+O5]中心的存在可以实现铁磁有序,从而产生室温铁磁性。随着超临界压力的增加,超临界CO2更容易破坏Mo-O键,从而在所需的居里温度(>380 K)下实现铁磁性能的增强。MoO3−x体系中的磁响应更接近自旋电子学的扩展。关键词:超临界CO2;室温铁磁性;二维;MoO3−x。
