Short range spin ice type correlations of HoAgGe by diffuse neutron scattering

Abstract: Spin ices are exotic phases of matter characterized by frustrated spins obeying local “ice rules” that minimize the number of spatially isolated magnetic monopoles, in analogy with the electric dipoles in water ice. In two dimensions, one can similarly define ice rules for in-plane Ising-like spins arranged on a kagome lattice, which could lead to a variety of unique orders and excitations. Based on single-crystal neutron diffraction results, we determine the magnetic structures of HoAgGe both at 10K and 4K, consistent with classical kagome spin ice predicted theoretically before. As far as we know this is the first time that such an order is observed in a naturally existing material. According to this scenario, above the long range magnetic order, there should be a short-range order satisfying the ice rule. To further verify such correlations, we plan to do diffuse neutron scattering.
