fit this paper, we report studies on the correlation between the presence and distribution of cation vacancies in doped manganites (La, M)MnO3+sigma (where M = Na, Ca) and their magnetic properties. Results indicate that cation vacancies are distributed differently for the different crystal structures and dopant ion type. In particular, it is shown that knowledge of the total vacancies concentration alone is not enough to Fully characterize the physical properties of rnanganites and that their distribution between the A and B sites of the perovskite structure plays a crucial role which should be taken into account in future studies.
