Novel spin textures in non-centrosymmetric magnet ScMnGe

The magnetism found in noncentrosymmetric magnetic materials has gained enormous interest because of the topologically nontrivial nanoscopic magnetic structures discovered that offer potential for new magnetic information manipulation and storage technologies. The noncentrosymmetric hexagonal ScFeGe reported to be an anisotropic metal with a transition to a weak itinerant incommensurate helimagnetic state below T_N = 36 K. We extend our magnetic and structural investigations of the helimagnetic non-centrosymmetric ScFeGe (achiral) studies to isostructural ScMnGe that crystallizes in the Fe₂P-type [ZrNiAl structure type, symmetry group P-62m] hexagonal crystal structure that is common among transition metal ternary compounds. The temperature dependence of the magnetic susceptibility and heat capacity (C_p)/T performed on polycrystalline samples of ScMnGe indicate a magnetic transition at T_N ~ 90 K with an upturn in c(T) and bump in Cp/T appear near ~40 K. In this talk, I will present the detailed magnetic and transport properties of ScMnGe which is also a weak itinerant magnetic system.
