Pyrochlore materials are known for their exotic magnetic and topological phases arising from complex interactions among electron correlations, band topology, and geometric frustration. Interfaces between different pyrochlore crystals characterized by complex many-body ground states hold immense potential for novel interfacial phenomena due to the strong interactions between these phases. However, the realization of such interfaces has been severely hindered by limitations in material synthesis methods.

Article Synopsis
  • Pyrochlore iridates are notable for studying complex phenomena due to their strong spin-orbit coupling, electronic interactions, and geometrically frustrated lattice structures.
  • In thin films of (111) YIrO with thicknesses ≤30 nm, researchers found a unique quantum disordered state at temperatures as low as 5 K, which was characterized by dispersionless magnetic excitations.
  • Below approximately 125 K, an anomalous Hall effect suggests the existence of chiral spin configurations, attributed to magnetic frustration in the lower-dimensional structure that leads to spin-liquid behavior without long-range order.

We report crystal growth, AC and DC magnetic susceptibilities [(, )], magnetization [(, )], and heat capacity [(, )] measurement results of GdSbTe single crystal. GdSbTe is isostructural to the confirmed nonmagnetic nodal-line semimetal ZrSiS of noncentrosymmetric tetragonal crystal structure in space group 4/ (No. 129), but it shows additional long-range antiferromagnetic spin ordering for the Gd spins of = / below T.
