AbstractIn 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.

Investigation of crystal structure, dielectric, magnetic and local ferroelectric properties of the diamagnetically substituted (1-x)BiFeO3-xBi (Ti0.5Ni0.5)O3solid solutions samples have been carried out. The solid solutions have been found to possess a rhombohedrally distorted perovskite structure described by the space group R3c. Compared with pure BiFeO3compound, both ferroelectric and magnetic properties are much improved by solid solution with Bi (Ti0.5Ni0.5)O3with saturation hysteresis loops observed. Among all the samples, thex=0.1 samples shows the optimal ferromagnetism with Mr~0.56531emμ/g and the optimal ferroelectricity with Pr~5.767μC/cm2 at room temperature.

Synthesis and characterization of (1E)-1-(4-chlorophenyl)-N-hydroxy-3-(1H-imidazol-1-yl)propan-1-imine (4) are reported. X-ray crystal structure of the title oxime4confirmed its assigned (E)-configuration. The compound crystallizes in the monoclinic space groupP21/cwitha=13.4292(3) Å,b=8.8343(2) Å,c=11.1797(3) Å,α=90°,β=108.873(2)°,γ=90°,V=1255.03(5) Å3, andZ=4. The molecules are packed in crystal structure by weak intermolecularO–H⋯Nhydrogen bonding interactions. Compound4is a useful intermediate for the synthesis of new imidazole-containing antifungal agents.
