SrCuTe 2 O 6 consists of a three-dimensional arrangement of spin-1 2 Cu 2+ ions. The first-, second-, and third-neighbor interactions, respectively, couple Cu 2+ moments into a network of isolated triangles, a highly frustrated hyperkagome lattice consisting of corner-sharing triangles and antiferromagnetic chains. Of these, the chain interaction dominates in SrCuTe 2 O 6 while the other two interactions lead to frustrated interchain coupling giving rise to long-range magnetic order at suppressed temperatures. In this paper, we investigate the magnetic properties in SrCuTe 2 O 6 using muon relaxation spectroscopy and neutron diffraction and present the low-temperature magnetic structure as well as the directional-dependent magnetic phase diagram as a function of field.

“…The 2 × 1 2 IR found for BaCuTe 2 O 6 contrasts with the 1 × 1 1 IR, recently found for the isostructural compound SrCuTe 2 O 6 [15,21], where the latter IR forbids both the (H, H, 0) and (H, H, H ) reflections. We therefore also refined the diffraction pattern of BaCuTe 2 O 6 using the 1 × 1 1 IR which gave the much worse goodness-of-fit of χ 2 = 8.5.…”

“…Recently a family of quantum magnets with chemical formula ACuTe 2 O 6 (A = Sr, Pb) was reported [15][16][17][18][19][20][21][22]. These compounds have cubic space group P4 1 32 where the magnetic Cu 2+ ions (S = 1/2) occupy the 12d Wyckoff site.…”

“…Despite the fact that Sr 2+ and Pb 2+ have very similar sizes, SrCuTe 2 O 6 and PbCuTe 2 O 6 have very different interaction strengths and thus magnetic properties. In SrCuTe 2 O 6 the third neighbor interaction is dominant and antiferromagnetic giving rise to spin-1/2 Heisenberg antiferromagnetic chains (HAFC), while the weaker first neighbor interactions act to couple these chains together and induce long-range magnetic order at a finite but suppressed Néel temperature (compared to the Curie-Weiss temperature) [15,18,19,21]. In contrast, for PbCuTe 2 O 6 the first and second neighbor interactions are strong, antiferromagnetic, and approximately equal to each other giving rise to a highly frustrated 3D network of corner-sharing triangles called the hyper-hyperkagome lattice (related to but distinctly different from the hyperkagome lattice), while the weaker third neighbor interactions act to reduce the degree of frustration [15,16].…”

We investigate the structural and magnetic properties of the quantum magnet BaCuTe 2 O 6 . This compound is synthesized in powder and single crystal form for the first time. Synchrotron x-ray and neutron diffraction reveal a cubic crystal structure (P4 1 32) where the magnetic Cu 2+ ions form a complex network. Heat capacity and static magnetic susceptibility measurements suggest the presence of antiferromagnetic interactions with a Curie-Weiss temperature of ≈− 33 K, while long-range magnetic order occurs at the much lower temperature of ≈6.3 K. The magnetic structure, solved using neutron diffraction, reveals antiferromagnetic order along chains parallel to the a, b, and c crystal axes. This is consistent with the magnetic excitations which resemble the multispinon continuum typical of the spin-1/2 Heisenberg antiferromagnetic chain. A consistent intrachain interaction value of ≈34 K is achieved from the various techniques. Finally the magnetic structure provides evidence that the chains are coupled together in a noncollinear arrangement by a much weaker antiferromagnetic, frustrated hyperkagome interaction.
