Abstract

The magnetic and structural properties of a single crystal of Pr_0.8Ca_0.2MnO₃ have been investigated by neutron powder diffraction and bulk magnetization as a function of temperature. Two ferromagnetic (FM) transitions near 140 and 70K, which are ascribed to the ordering of Mn and Pr spins, respectively, are clearly evidenced by both measurements. The low temperature FM transition is largely dependent upon a strong exchange coupling between the localized Pr 4f and the neighboring itinerant Mn 3d spins. Near 140K distinctive changes occur in lattice parameters, whereas no anomalous variation develops near 70K.
