We present DC magnetic susceptibility, X-ray diffraction, and electron-spin
resonance (ESR) studies in LaMnO3+delta (- 0.01 less than or equal to delt
a less than or equal to 0.07). Special attention was given to the correlati
on between the Jahn-Teller distortions of the lattice and the anisotropic c
ontributions to the ESR line width. (C) 2000 Elsevier Science B.V. All righ
