Description

We present a plausible explanation for the intriguing phase separation phenomena displayed by Pr0.50Ca0.50Mn1-xMxO3 compounds. This explanation is based on the simulations that authors have recently published (2008 Europhys. Lett. 84 67011). The results obtained there are compared with those found for M = Ti by means of neutron and synchrotron X-ray powder diffraction. Phase separation can be explained from very local effects of M ions together with their random distribution in Mn sites.
