Topological metamagnetism: Thermodynamics and dynamics of the transition in spin ice under uniaxial compression

Metamagnetic transitions are analogs of a pressure-driven gas-liquid transition in water. In insulators, they marked by superlinear increase the magnetization that occurs at field strength set spin exchange interactions. Here we study topological metamagnets, which is itself quantity and for find single line two materials with substantially different magnetic interactions: ices ${\mathrm{Dy}}_{2}{\mathrm{Ti}}_{2}{\mathrm{O}}_{7}$ ${\mathrm{Ho}}_{2}{\mathrm{Ti}}_{2}{\mathrm{O}}_{7}$. We crystals under stress applied along [001] direction show this transition, Kasteleyn type, has versus curve upward convexity distinctive asymmetric peak susceptibility. also dynamical response ${\mathrm{Ho}}_{2}{\mathrm{Ti}}_{2}{\mathrm{O}}_{7}$ sensitive to changes ${\mathrm{Ho}}^{3+}$ environment induced compression [001]. Uniaxial may open up experimental access equilibrium properties ice lower temperatures.
