Abstract

In this paper, phase separation and crystal structure of (x) La0.625Sr0.375MnO3 − (1-x) LuMnO3 system (LSMO-LMO), and (1-x) La0.9Ca0.1MnO3-(x) LuMnO3 system (LCMO-LMO) were studied by XRD and SEM. The results confirm that there are solid solutions in both of these two systems. There is a solid solution of monoclinic phase of space group P1121/a for x=0.980∼1.0 in LSMO-LMO system. There is a solid solution of hexagonal phase of space group P63cm for x=0.0∼0.24 in LCMO-LMO. Selected compositions were tested in terms of their magnetization, dielectric constant and ferroelectric properties at low temperatures.
