Abstract
We report the crystal growth and characterization of a rare-earth-containing material, Dy<sub>3.00(1)</sub>Pt<sub>2</sub>Sb<sub>4.48(2)</sub>. This compound possesses a similar structure to the previously reported Y<sub>3</sub>Pt<sub>4</sub>Ge<sub>6</sub>, but it lacks two layers of Pt atoms. Crystallographic disorder was found in Dy<sub>3.00(1)</sub>Pt<sub>2</sub>Sb<sub>4.48(2)</sub>. Additionally, the Dy-Dy framework was found to have both square net and triangular lattices. Dy<sub>3.00(1)</sub>Pt<sub>2</sub>Sb<sub>4.48(2)8</sub> was determined to be antiferromagnetically ordered around ∼15 K while a competing antiferromagnetic sublattice also exists at lower temperature. Strong magnetic anisotropy was observed, and several metamagnetic transitions were seen in the hysteresis loops. Furthermore, the Curie-Weiss fitting revealed an unusually small effective moment of Dy, which is far below the expected value of Dy<sup>3+</sup> (10.65 μ<sub>B</sub>). This material might provide a new platform to study the relationship between crystallographic disorder and magnetism.
