  Rare-earth orthoferrite RFeO3 materials such as NdFeO3 are strongly studied
because of their fascinating magnetic properties and their potential
applications. Here, we show the successful epitaxial synthesis of
parasitic-free NFO thin film by pulsed laser deposition on (001)-SrTiO3.
High-resolution X-ray diffraction shows a coherent growth and a tetragonal-like
structure of a tensile strained 80 nm thick NFO film in contrast with the bulk
orthorhombic state. Room temperature magnetometry indicates a bulk-like
antiferromagnetic state for the NFO film. Temperature-dependent X-ray
diffraction and magnetometry highlight a significant spin-lattice coupling at
the Neel Temperature while a new magneto-structural instability is discovered
around 250{\deg}C that needs further investigation.
