    • Comparison of surface spin wave modes at Fe/MnF2 and Fe/Mn interfaces 

      Siu, I.L.; Islam, M.N.; Walker, J.C. (American Institute of Physics, 2000-11-01)
      We have studied the thermal demagnetization in semi-infinite ferromagnets in Fe/MnF2 and Fe/Mn bilayers using Mössbauer spectroscopy. We find that the hyperfine field at the Fe/MnF2 interface follows a quasilinear temperature ...
    • Magnetically driven ferroelectric order in Ni3V2O8 

      Lawes, G.; Harris, A.B.; Kimura, T.; Rogado, N.; Cava, R.J.; Aharony, A.; Entin-Wohlman, O.; Yildirim, T.; Kenzelmann, M.; Broholm, C.; Ramirez, A.P. (American Physical Society, 2005-08-19)
      We show that long-range ferroelectric and incommensurate magnetic order appear simultaneously in a single phase transition in Ni3V2O8. The temperature and magnetic-field dependence of the spontaneous polarization show a ...
    • Memory effects of exchange coupling in CoO/Ni81Fe19 bilayers 

      Gokemeijer, N.J.; Chien, C.-L. (American Institute of Physics, 1999-04-15)
      By changing the field-cooling procedure, the value and even the sign of the exchange field HE in CoO/Ni81Fe19 bilayers can be greatly altered. The value of HE can be made to vanish at any temperature below TN. We also show ...
    • Studies of deposition order anomaly of exchange coupling in bilayers and trilayers of NiFe and CoO 

      Ambrose, T.; Leifer, K.; Hemker, K.J.; Chien, C.-L.; Ambrose, T.1; Leifer, K.; Hemker, K.J.; Chien, C.L. (American Institute of Physics, 1997-04-15)
      The temperature dependence of the exchange field and coercivity and the effect of deposition order have been studied in a series of bilayer (NiFe/CoO and CoO/NiFe) and trilayer (NiFe/CoO/NiFe) films. A profound difference ...
