Unconventional critical behavior in quasi-one-dimensional $S$ = 1 chain NiTe${}_2$O${}_5$

Abstract

Here we report a new quasi-one-dimensional $S$ = 1 chain compound NiTe${}_2$O${}_5$. From the comprehensive study of the structure and magnetic properties on high quality single crystalline NiTe${}_2$O${}_5$, it's revealed that NiTe${}_2$O${}_5$ undergoes a transition into an intriguing long-range antiferromagnetic order at $T_{\mathrm{N}}=30.5\mathrm{K}$, in which longitudinal magnetic moments along the chain direction are ferromagnetically ordered, while their transverse components have an alternating ferromagnetic-antiferromagnetic coupling. Even though the temperature dependence of magnetic susceptibility represents an archetypal anisotropic antiferromagnetic order, we found that critical behavior of unconventional nature with ${\alpha }^{\prime }\sim 0.25$ and $\beta \sim 0.18$ is accompanied by the temperature evolution of the antiferromagnetic order parameter.
