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