Field-induced magnetic phase transitions and metastable states in Tb 3 Ni

摘要: In this paper we report the detailed study of magnetic phase diagrams, low-temperature structures, and field effect on electrical resistivity binary intermetallic compound ${\mathrm{Tb}}_{3}\mathrm{Ni}$. The incommensurate structure spin-density-wave type described with superspace group $P{112}_{1}/a{1}^{\ensuremath{'}}(ab0)0ss$ propagation vector ${\mathbf{k}}_{\mathrm{IC}}=\left[0.506,0.299,0\right]$ was found to emerge just below N\'eel temperature ${T}_{\mathrm{N}}=61$ K. Further cooling 58 K results in appearance multicomponent states: (i) a combination ${\mathbf{k}}_{1}=\left[\frac{1}{2},\frac{1}{2},0\right]$ ${\mathbf{k}}_{\mathrm{IC}}$ range $51lTl58$ K; (ii) mixed state ${\mathbf{k}}_{\mathrm{IC}}, {\mathbf{k}}_{1}$, ${\mathbf{k}}_{2}=\left[\frac{1}{2},\frac{1}{4},0\right]$ partially locked-in component $48lTl51$ (iii) that is by intersection two isotropy subgroups associated irreducible representations coupled primary order parameters (OPs) ${\mathbf{k}}_{3}=\left[\frac{1}{2},\frac{1}{3},0\right]$ involves secondary OPs ${\mathbf{k}}_{4}=\left[\frac{1}{2},0,0\right]$ 48 An external suppresses complex antiferromagnetic states induces metamagnetic transitions towards forced ferromagnetic are accompanied substantial magnetoresistance due superzone effect. induced after application an along $b$ $c$ crystallographic axes be irreversible 3 8 K, respectively.
