摘要：

Conventional phase transitions are well understood in terms of the order parameter, based on the Landau-Ginzburg-Wilson theory. However, unconventional magnetic orders have been observed in clean systems such as MnSi. The unconventional magnetic orders of conduction electrons in the metallic phase has been observed for high-temperature superconductors and heavy fermion compounds. However, these unconventional magnetic orders have been limited to relatively low temperatures as quantum phase transitions. Here high-temperature magnetic short-range order is observed as one of the unconventional magnetic orders at temperatures up to 720K in a noncentrosymmetric intermetallic antiferromagnet Mn3RhSi with a well-ordered lattice. The magnetic Mn ions form a hyperkagome network of corner-sharing triangles, where the spins are geometrically frustrated. The spin network is equivalent to that of a spin liquid and non-Fermi-liquid material, beta -Mn. Our observation indicates that a metallic phase with magnetic short-range order exists at high temperatures. Magnetic short-range ordering has been observed at low temperatures as quantum phase transitions in some compounds. Here, magnetic short-range ordering is found to remain at temperatures up to 720K in noncentrosymmetric Mn3RhSi.
