| contents | We report on the magnetic and electrical properties of a (Mn$_3$Sn)$_2$ triangular network kagome structured high quality Ho substituted ErMn$_6$Sn$_6$ single-crystal sample by magneto-transport measurements. Er$_{0.5}$Ho$_{0.5}$Mn$_6$Sn$_6$ orders antiferromagnetically at Néel temperature $T_\mathrm{N} \sim$ 350 K followed by a ferrimagnetic (FiM) transition at $T_\mathrm{C} \sim$ 114 K and spin-orientation transition at $T_\mathrm{t} \sim$ 20 K. The field-manifestations of these magnetic phases in the \textit{ab}-basal plane and along the \textit{c}-axis are illustrated through temperature-field \textit{T-H} phase diagrams. In \textit{H}$\parallel$\textit{c}, narrow hysteresis between spin reorientation and field-induced FiM phases below $T_\mathrm{t}$, enhanced/strengthened FiM phase below $T_\mathrm{C}$ and stemming of FiM phase out of strongly coexisting AFM and FiM phases below $T_\mathrm{N}$ through a non-meta-magnetic transition are confirmed to arise from strong R-Mn sublattices interaction. In contrast, \textit{H}$\parallel$\textit{ab}-plane, between $T_\mathrm{N}$ and $T_\mathrm{C}$, individually contributing R-Mn sublattices with weak antiferromagnetic interactions undergo a field-induced spin-flop quasi-metamagnetic transition to FiM state. The temperature dependent electrical resistivity suggests metallic nature with Fermi liquid behavior at low temperatures. Essentially, the current study stimulates interest to investigate the magnetic and electrical properties of mixed rare-earth layered kagome magnetic metals for possible novel and exotic behavior. |
