摘要:

本文报道了用低温磁力显微镜对两种不同来源的MnSb_2Te_4单晶中的铁磁畴进行的磁成像。的磁场依赖的领域揭示了非常弱的钉扎的域壁在MnSb2Te 4,导致在一个可忽略的小磁滞回线。畴衬度的温度依赖性揭示了平均场的行为,在良好的协议与体磁化测量。

英文摘要:

We report the magnetic imaging of ferromagnetic domains in the van der Waals single crystal MnSb2Te4 from two different sources using cryogenic magnetic force microscopy. The magnetic field dependence of the domains reveals very weak pinning of domain walls in MnSb2Te4, resulting in a negligibly small magnetic hysteresis loop. The temperature dependence of the domain contrast reveals a mean field like behavior, in good agreement with that of bulk magnetization measurements.
