Abstract:

EPR measurements at room temperature (RT) on the oxygen deficient (La, Tm)-Ba-Cu-O compound (tetragonal phase) revealed a line centered at g=2.895(5) with linewidth ΔH=0.015(1)T. The line is ascribed to Tm2+ ions (4f13, 2F7/2) assuming that the Γ(7) doublet is the ground state. A characteristic EPR spectrum of divalent copper ions was also observed. © 1992.
