Abstract
A growth diagram of Lu-Fe-O compounds on an MgO (111) substrate using pulsed laser deposition
is constructed according to the experimental data. The LuFe2O4 phase can only be grown in a
small range of temperature and O2 pressure conditions. Fundamental understanding of the growth
mechanism of Lu-Fe-O compound films are gained in terms of the thermal chemistry at the surface.
Superparamagnetism is observed in a film of LuFe2O4 clusters separated by the hexagonal LuFeO3
phase and structural defects.
