摘要:

通过测量Yb_2Pd_2Sn在5.0GPa压力下的电阻率发现了压力诱导的长程反铁磁有序。在约1.0 GPa以上观察到磁有序,这是Yb-金属间化合物中显示压力诱导磁有序的最低压力。出乎意料的是,在约4.0 GPa以上有序消失,导致首次观察到在单一材料内的宽压力范围内持续存在两个量子临界点的出现。

英文摘要:

Pressure induced long range antiferromagnetic order is discovered in Yb2Pd2Sn by measuring the electrical resistivity under pressure up to 5.0 GPa. Magnetic ordering is observed above about 1.0 GPa, being the lowest pressure in Yb-intermetallics showing pressure induced magnetic ordering, Unexpectedly, ordering disappears above about 4.0 GPa, giving rise to the first observation of the appearance of two quantum critical points persisting in a broad range of pressure within a single material.
