Here, we report magnetic susceptibility χ, isothermal magnetization M, heat capacity C_p, and electrical resistivity ρ measurements on undoped EuMn₂As₂ and K-doped Eu_0.96K_0.04Mn₂As₂ and Eu_0.93K_0.07Mn₂As₂ single crystals with the trigonal CaAl₂Si₂-type structure as a function of temperature T and magnetic field H. EuMn₂As₂ has an insulating ground state with an activation energy of 52 meV and exhibits antiferromagnetic (AFM) ordering of the Eu⁺² spins S=7/2 at T_N1=15 K from C_p(T) and χ(T) data with a likely spin-reorientation transition at T_N2=5.0 K. The Mn⁺² 3d⁵ spins-5/2 exhibit AFM ordering at T_N=142 K from all three types of measurements. The M(H) isotherm and χ(T) data indicate that the Eu AFM structure is both noncollinear and noncoplanar. The AFM structure of the Mn spins is also unclear. A 4% substitution of K for Eu in Eu_0.96K_0.04Mn₂As₂ is sufficient to induce a metallic ground state. We found evidence for a difference in the AFM structure of the Eu moments in the metallic crystals from that of undoped EuMn₂As₂ versus both T and H. For metallic Eu_0.96K_0.04Mn₂As₂ and Eu_0.93K_0.07Mn₂As₂, an anomalous S-shape T dependence of ρ related to the Mn magnetism is found. Upon cooling from 200 K, ρ exhibits a strong negative curvature, reaches maximum positive slope at the Mn T_N≈150 K, and then continues to decrease but more slowly below T_N. Finally, this suggests that dynamic short-range AFM order of the Mn spins above the Mn T_N strongly suppresses the resistivity, contrary to the conventional decrease of ρ that is only observed upon cooling below T_N of an antiferromagnet.
