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 ₂O 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 the LuFe ₂O ₄ film and is explained in terms of the effect of the impurity hexagonal LuFeO ₃ (h-LuFeO ₃) phase and structural defects.
