Zigzag magnetic order in a novel tellurate compound Na${}_{4-\delta }$NiTeO${}_6$ with $S$ = 1 chains

Abstract

Na${}_{4-\delta }$NiTeO${}_6$ is a rare example in the transition-metal tellurate family of realizing an $S$ = 1 spin-chain structure. By performing neutron powder diffraction measurements, the ground-state magnetic structure of Na${}_{4-\delta }$NiTeO${}_6$ is determined. These measurements reveal that below $T{}_{\mathrm{N}}$ $\sim$ 6.8(2) K, the Ni${}^{2+}$ moments form a screwed ferromagnetic (FM) spin-chain structure running along the crystallographic $a$ axis but these FM spin chains are coupled antiferromagnetically along the $b$ and $c$ directions, giving rise to a magnetic propagation vector of $k$ = (0, 1/2, 1/2). This zigzag magnetic order is well supported by first-principles calculations. The moment size of Ni${}^{2+}$ spins is determined to be 2.1(1) $\mu$${}_{\mathrm{B}}$ at 3 K, suggesting a significant quenching of the orbital moment due to the crystalline electric field (CEF) effect. The previously reported metamagnetic transition near $H{}_{\mathrm{C}}$ $\sim$ 0.1 T can be understood as a field-induced spin-flip transition. The relatively easy tunability of the dimensionality of its magnetism by external parameters makes Na${}_{4-\delta }$NiTeO${}_6$ a promising candidate for further exploring various types of novel spin-chain physics.
