In orthoferrites the rare-earth (R) ion has a big impact on structural and magnetic properties in particular ionic size influences octahedral tilt R3+- Fe3+ interaction modifies like spin reorientation. Growth induced strain thin films is another means to modify materials since sign of affects bond length therefore directly orbital interaction. Our study focuses epitaxially grown (010) oriented DyFeO3 LuFeO3 films, thereby investigating compressive lattice magnetically active Dy3+ inactive Lu3+ compared uniaxially strained single crystal DyFeO3. The exhibits shift more than 20K spin-reorientation temperatures, maintain antiferromagnetic {\Gamma}4 phase Fe-lattice below reorientation, show double step hysteresis loops for both in-plane directions between 5 K 390 K. This signature an Fe-spin ferromagnetic above N\'eel temperature Dy. observed film reorientation temperatures vs good agreement with isostatic neutron diffraction experiments rate 2 K/ kbar bar.
