    • Magnetic dynamics of La2CuO4 studied by Mossbauer spectroscopy 

      Tang, H.; Gang, X.; Singh, A.; Tesanovic, Z.; Chien, C.-L.; Walker, J.C. (American Institute of Physics, 1990-05-01)
      By doping a very small amount of 57Fe into La2CuO4, Mossbauer spectroscopy has been applied to study the magnetic property of the parent compound. From the measurement of the magnetic hyperfine field at the Fe nuclei for ...
    • A strongly fluctuating quasi-two-dimensional insulator 

      Cooper, A.S.; Espinosa, G.P.; Broholm, C.; Aeppli, G. (American Institute of Physics, 1991-04-15)
      The authors describe neutron-scattering data for SrCr8-xGa4+xO19, a layered compound containing planes of S=3/2 Cr3+ ions which form Kagome lattices. Despite strong antiferromagnetic interactions (θCW≈-500 K), fluctuations ...
