Lanthanum Influence on EuAlO3 Perovskite Structural Properties : Experimental and Molecular Dynamics Studies

Abstract EN

X-ray diffraction, 27Al MAS NMR, and FTIR spectra along with results of molecular dynamics simulations were used to characterise LaxEu1−xAlO3 perovskites for x=0.3, 0.1.

Experimental and simulation results show that local changes in the perovskite-like structure can be achieved as lanthanum ions substitute europium ones.

The introduction of La3+ ions in the EuAlO3 parent causes an increase in the mobility of oxygen network.
