We report on single-crystal growths of the SrTb 2 O 4 compound by a super-necking technique with a laser-floating-zone furnace and study the stoichiometry, growth mode, and structural and magnetic properties by scanning electronic microscopy, neutron Laue, X-ray powder diffraction, and the physical property measurement system. We optimized the growth parameters, mainly the growth speed, atmosphere, and the addition of a Tb 4 O 7 raw material. Neutron Laue diffraction displays the characteristic feature of a single crystal. Our study reveals an atomic ratio of Sr:Tb = 0.97(2):2.00(1) and a possible layer by layer crystal growth mode. Our X-ray powder diffraction study determines the crystal structure, lattice constants, and atomic positions. The paramagnetic (PM) Curie–Weiss (CW) temperature θ CW = 5.00(4) K, and the effective PM moment M mea eff = 10.97(1) μ B per Tb 3+ ion. The data of magnetization versus temperature can be divided into three regimes, showing a coexistence of antiferromagnetic and ferromagnetic interactions. This probably leads to the magnetic frustration in the SrTb 2 O 4 compound. The magnetization at 2 K and 14 T originates from both the Tb1 and Tb2 sites and is strongly frustrated with an expected saturation field at ∼41.5 T, displaying an intricate phase diagram with three ranges.

“…The structures of Ni 2 (PO 4 )(OH) and Ni 7 (PO 4 ) 3 (HPO 4 )(OH) 3 were refined in the polar space groups P31m and P6 3 mc, respectively. The correct absolute structures were supported by their respective Flack parameters of 0.02(2) and 0.007 (12). Details of the structure refinements are given in Table 1.…”

“…Phosphates also offer an entry point to then explore the direct isoelectronic comparison to arsenates and vanadates, which surprisingly often display quite different magnetic behavior. 12 Herein we report three new structural types featuring quasi-1-D nickel oxide chains with various phosphate bridging behavior, Ni 2 (PO 4 )(OH) (I), Ni 7 (PO 4 ) 3 (HPO 4 )(OH) 3 (II), and NaNiPO 4 (III). These compounds exhibit complex structures and varied magnetic behavior.…”

Three novel nickel-phosphate structures are reported, Ni2(PO4)(OH) (I), Ni7(PO4)3(HPO4)(OH)3 (II), and NaNiPO4 (III). Each new system was prepared via a high-temperature hydrothermal synthesis at 600–650 °C. All three compounds are built of quasi-one-dimensional (quasi-1-D) Ni2+ containing chains with varying phosphate bridging modes and were characterized by single crystal X-ray diffraction and magnetic susceptibility. All three compounds display very different magnetic behavior. Anisotropic magnetic data is reported for Ni2(PO4)(OH) (I) exhibiting slow antiferromagnetic ordering in the high-temperature regime with substructures that begin to form below 32 K at different field strengths. These characteristics affirm I as being one of the few Haldane-like material candidates. The Ni7(PO4)3(HPO4)(OH)3 (II) material is a member of the unusual ellenbergerite structural family and displays complex inter- and intrachain magnetic interactions while NaNiPO4 (III) shows antiferromagnetic ordering near 18 K. This magnetic behavior is correlated with their structures.
