The role of 5d electrons of transition metals in double perovskites Cs2ZCl/Br6 (Z = Ta, W) has been probed for advanced spintronic technology. The magnetic and transport properties are computed by using Wein2K code and BoltzTraP code. The exchange mechanism is explained by the measurement of crystal field energy, exchange energy and hybridization process. The half metallic ferromagnetism is illustrated by double-exchange model and exchange constants while spin polarization is illustrated by integer value of total magnetic moments and polarization factor computations. The issue of stability is clarified by formation energy and tolerance factor conditions. In the end, thermoelectric properties are analyzed by thermal to electrical conductivity ratio, Seebeck coefficient, and power factor.
