No full textIn perovskite oxide materials, because of
the insertion of multiple valence states ions (e.g., Mn
in manganites) at atomic A-site (i.e., at the center of
perovskite cubic cell), an enhancement of the ferromagnetic
metallic state together with a strong orbital
order of Mn-ions is established. Such a feature goes
beyond the conventional theoretical framework for
which the kinetic energy of the free charge carriers
prevents the occurrence of a long-range orbital order.
We do provide a complete physical characterization of
these so-called A-site manganites by comparing
transport and structural properties of La0.7Sr0.3MnO3
and LaMnO3 thin films with different excess Mn
content and different oxygen content. A viable route to
successfully grow such class of materials as a function
of temperature and oxygen environment is provided.
The observed multi-order phase coexistence opens
unexplored perspectives toward the synthesis of new
intrinsic multi-functional materials
