Crystal field excitations and magnons : their roles in oxyselenides Pr2O2M2OSe2 (M = Mn, Fe).

Oogarah, R. K. and Stockdale, C. P. J. and Stock, C. and Evans, J. S. O. and Wills, A. S. and Taylor, J. W. and McCabe, E. E. (2017) 'Crystal field excitations and magnons : their roles in oxyselenides Pr2O2M2OSe2 (M = Mn, Fe).', Physical review B., 95 (17). p. 174441.


We present the results of neutron scattering experiments to study the crystal and magnetic structures of the Mott-insulating transition metal oxyselenides Pr2O2M2OSe2 (M = Mn, Fe). The structural role of the non-Kramers Pr3+ ion was investigated, and analysis of Pr3+ crystal field excitations was performed. Long-range order of Pr3+ moments in Pr2O2Fe2OSe2 can be induced by an applied magnetic field.
