Title: Electronic and Magnetic States of Pr and Mn in the Pr{sub 1–x}Sr{sub x}MnO{sub 3} Films Studied by XANES and XMCD Spectroscopy

Abstract

The spectral dependences of X-ray absorption near-edge spectroscopy (XANES) and X-ray magnetic circular dichroism (XMCD) and the field dependences of XMCD near the K edge of Mn and the L{sub 2,3} edges of Pr in the Pr{sub 0.8}Sr{sub 0.2}MnO{sub 3} and Pr{sub 0.6}Sr{sub 0.4}MnO{sub 3} films at T = 90 K are studied. The spectral dependences point to a mixed valence state of Mn and Pr in the films. It is found that, as compared to XANES, XMCD is more sensitive to the valence state of Pr{sup 4+}. The field dependences of XMCD point to ferromagnetic behavior of Mn ions and the Van Vleck paramagnetism of Pr ions, which makes a significant contribution to the total magnetization of the films. It is shown that as the Sr concentration increases, the XMCD intensity at the K edge of Mn increases, which indicates a growth of the total magnetic moment of the film due to an increase in the 4p–3d hybridization.
