Abstract

We report the crystal growth and characterization of a rare-earth-containing material, Dy_3.00(1)Pt₂Sb_4.48(2). This compound possesses a similar structure to the previously reported Y₃Pt₄Ge₆, but it lacks two layers of Pt atoms. Crystallographic disorder was found in Dy_3.00(1)Pt₂Sb_4.48(2). Additionally, the Dy-Dy framework was found to have both square net and triangular lattices. Dy_3.00(1)Pt₂Sb_4.48(2)8 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 Dy³⁺ (10.65 μ_B). This material might provide a new platform to study the relationship between crystallographic disorder and magnetism.
