Soft x-ray magnetic circular dichroism study of Ca_1-xSr_xRuO_3 across the ferromagnetic quantum phase transition
J. Okamoto, T. Okane, Y. Saitoh +10
Ca_1-xSr_xRuO_3, which is ferromagnetic for Sr concentration x > 0.3, has been studied by x-ray magnetic circular dichroism (XMCD) in Ru 3p and O 1s core-level x-ray absorption. XM…
A muon-spin relaxation study of BiMnO3
T. Lancaster, S. J. Blundell, P. J. Baker +5
We present the results of muon-spin relaxation measurements on ferromagnetic BiMnO3. Below T_C=98.0(1) K oscillations in the time-dependence of the muon polarization are observed,…
Angle-resolved photoemission studies of lattice polaron formation in the cuprate Ca2CuO2Cl2
K. M. Shen, F. Ronning, W. Meevasana +10
To elucidate the nature of the single-particle excitations in the undoped parent cuprates, we have performed a detailed study of Ca2CuO2Cl2 using photoemission spectroscopy. The ph…
Valence changes associated with the metal-insulator transition in BiLaNiO
H. Wadati, M. Takizawa, T. T. Tran +9
Perovskite-type BiNiO is an insulating antiferromagnet in which a charge disproportionation occurs at the Bi site. La substitution for Bi suppresses the charge disproportionati…
