abstract = {Microstructural properties of spinel LiFe5O8 (LFO) films
grown on (001)-oriented SrTiO3 (STO) substrates have been
investigated at the atomic-scale by advanced electron
microscopy techniques. Two types of orientation relationship
(OR) between the LFO films and the STO substrates have been
determined, cube-on-cube and (111)[ 10]LFO//(111)[1 0]STO.
Antiphase boundaries (APBs) and three types of twin
boundaries (TBs) form within the LFO films, and the
propagation of TBs and APBs results in their complex
interactions. In most cases, interactions between TBs and
APBs change the type of TBs and terminate the propagation of
APBs since the APBs introduce a displacement vector of
(a/4)〈110〉 into the TBs. In addition, the interactions
between two coherent TBs are observed to generate the
incoherent TB. The epitaxial strain of the LFO/STO (001)
heterosystem can be released by the formation of TBs and
APBs in the films and misfit dislocations at the interface.
Considering that the magnetic coupling across the APBs and
TBs can lead to novel physical properties, the appearance of
APBs and TBs with a high density in the LFO films would
affect the magnetic properties of the films.},
