We report structure, electrical resistivity and thermopower of polycrystalline SmFe1-x CoxAsO samples for 0.0 ≤ x ≤ 0.3. The XRD data revealed full Co substitution at Fe-site with slight compression of the unit cell. Resistivity data showed that

The realization of spin-glass (S-G) state in Heusler alloys is very rare despite the presence of inherent structural and elemental disorder in those compounds. Although a few half and full Heusler alloys are known to exhibit S-G state, there is hardl
