Abstract

A growth diagram of Lu-Fe-O compounds on MgO (111) substrates using pulsed laser deposition is constructed based on extensive growth experiments. The LuFe $_2$ O $_4$ phase can only be grown in a small range of temperature and O $_2$ pressure conditions. An understanding of the growth mechanism of Lu-Fe-O compound films is offered in terms of the thermochemistry at the surface. Superparamagnetism is observed in LuFe $_2$ O $_4$ film and is explained in terms of the effect of the impurity h-LuFeO $_3$ phase and structural defects .
