Study of the magneto-electronic, optical, thermal and thermoelectric applications of double perovskites BaMTaO (M = Er, Tm).

The structural, electronic, optical, thermodynamic and thermoelectric properties of double perovskites BaMTaO (M = Er, Tm) have been studied. These alloys stabilize in cubic structure with paramagnetic phases and structural parameters that are in good agreement with experimental results. The elastic parameters reveal both materials as being super hard and brittle in nature.
