    • Spin-lattice order in frustrated ZnCr2O4 

      Ji, S.; Lee, S.-H.; Broholm, C.; Koo, T.Y.; Ratcliff, W.; Cheong, S.-W.; Zschack, P. (American Physical Society, 2009-07-17)
      Using synchrotron x-ray and neutron diffraction, we disentangle spin-lattice order in highly frustrated ZnCr2O4 where magnetic chromium ions occupy the vertices of regular tetrahedra. Upon cooling below 12.5 K the quandary ...
    • Strong magnetic fluctuations in transition metal oxides 

      Aeppli, G.; Lee, S.-H.; Broholm, C.; DiTusa, J.F.; Bao, W. (American Institute of Physics, 1996-04-15)
      Most magnets have long-range magnetic order when the thermal energy is less than the local magnetic exchange energy (T<|ΘCW|) effects such as reduced dimensionality and frustration, 1 however, can suppress the ordering ...
