Abstract

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.
