We explored the magnetostructural interplay in two halide double perovskites semiconductors, Cs₂NaFeCl₆ and Cs₂AgFeCl₆, with Raman spectroscopy, thermal expansion and magnetostriction measurements and found a connection between the strength of the exchange interaction and magnetoelastic coupling with the structural and magnetic ordering.
