Structure-Property Relationships in Tb₄PtGa₁₂ and Y₄PtGa₁₂

Abstract

Single crystals of Y4PtGa12 have been synthesized and characterized by X-ray diffraction. The compound crystallizes in the cubic Im3m space group with lattice parameters a = 8.530(5) Å. Magnetic property measurements show that Y4PtGa12 does not order magnetically. Structure-property relationships with the isostructural antiferromagnet Tb4PtGa12 are discussed.

A new family of heavy-fermion compounds: U4TGa12 (T=Fe, Co, Rh and Pd)

“…So far, the magnetic properties of 4:1:12 compounds are only known for Tb 4 PdGa 12 and Tb 4 PtGa 12 that both order antiferromagnetically at T N = 16 and 12 K and display metamagnetic transitions at 0 H c ≈ 5 and 0.3 T, respectively [24,25]. Similarly, U 4 PdGa 12 also orders antiferromagnetically, at T N = 43 K, but does not show any metamagnetic transitions up to μ 0 H c = 9 T.…”

“…Recently, the first physical measurements of 4:1:12 compounds were reported on two isotype compounds, Tb 4 PdGa 12 and Tb 4 PtGa 12 . They both order antiferromagnetically at T N = 16 and 12 K and present metamagnetic transitions at μ 0 H c ≈ 5 and 0.3 T, respectively [24,25].…”
