A A schematic of the TM spin center embedded in a spin-rich-host cubic halide double perovskites Cs2(Na:Ag)InCl6. B A representative picture of the TM spin center, coupled with the nearest neighbor 35,37Cl and the next nearest neighbor 133Cs nuclear spins through hyperfine interactions. The white and black dotted lines represent the principal directions of the hyperfine interaction with the 35,37Cl and 133Cs nuclei, respectively. C cw-EPR spectra of Cr[Na] and Fe[Na] powder samples, measured at room temperature and a microwave frequency of 9.77 GHz.
