| contents | Transition-metal oxides with an ABO$_3$ perovskite structure exhibit significant coupling between spin, orbital, and lattice degrees of freedom, highlighting the crucial role of lattice distortion in tuning the electronic and magnetic properties of these systems. In this study, we grow a series of antiferromagnetic GdVO$_3$ thin films on different substrates introducing various strain values. The results demonstrate that the strain not only affects the material's structure and magnetic transition temperature but also influences the growth direction of the orthorhombic unit cell. A correlation is observed between the orientation of the orthorhombic long axis direction and the material's Néel temperature. DFT calculations highlighting the link between strain, lattice distortions and magnetic characteristics confirm these conclusions. Our findings demonstrate that the development of novel features in RVO$_3$ through material design requires control of growth orientation through strain engineering. |
