研究发现可控插层的CrTa₃S₆粉末中,Cr插层量低于0.996时出现手性螺旋磁有序,高于1.000时为铁磁性,该螺旋磁周期的演化与样品尺寸相关。
AI 中文摘要
我们报道了手性插铬过渡金属二硫族化合物CrₓTa₃S₆的磁性发生高度敏感的变化。磁化曲线和小角中子散射数据显示,当Cr插层量x低于0.996时,粉末样品表现出手性螺旋磁性;而当x高于1.000时,样品表现出铁磁性。关于螺旋磁周期的出现及其随温度的演化,本文结合粉末和微加工晶体的样品尺寸进行了讨论。
英文摘要
We report a highly sensitive change in magnetic properties of a chiral Cr-intercalated transition-metal dichalcogenide Cr$_{x}$Ta$_{3}$S$_{6}$. Magnetization curves and small-angle neutron scattering data revealed that the powder samples exhibit chiral helimagnetism with a Cr intercalation quantity $x$ below 0.996, while they show ferromagnetism above 1.000. The emergence and temperature-dependent evolution of the helimagnetic period are argued in terms of sample dimensions of powders and microfabricated crystals.
