AB  - We report on the structure, spin-lattice and magneto-electric coupling in 
      (1-x)Pb(Fe(2/3)W(1/3))O(3)-(x)BiFeO(3)(wherex= 0.1 and 0.4) (PBFW) solid solution 
      synthesized through two-step solid-state reaction method. The room temperature 
      (RT) crystallographic studies were carried out using x-ray diffraction and 
      neutron diffraction measurements which show a single-phasePseudocubiccrystal 
      system withPm-3mspace group. Rietveld refinement was carried out to obtain the 
      structural parameters usingFullprofsoftware and the observed structural 
      parameters are in good agreement with the previous reports. Temperature-dependent 
      neutron diffraction measurements reveal the presence of commensurate G-type 
      antiferromagnetic structure. The magnetic structure was analyzed using the 
      propagation wave vectork approximately  ((1/2) (1/2) (1/2)) for both the solid solutions. The obtained 
      lattice constants increase linearly and the magnetic moment decrease with 
      temperature, which shows a remarkable anomaly around the magnetic (T(N) approximately  405 K 
      forx= 0.1 and 531 K forx= 0.4) transition temperatures. This anomaly clearly 
      indicates the existence of spin-lattice and magnetoelectric coupling. The 
      magnetic susceptibility (ZFC and FC at 500 Oe) andM-Hhysteresis loop measurements 
      show spontaneous magnetic moment due to the Fe(3+)-O(2-)-Fe(3+)superexchange 
      interaction coexisting with the weak ferromagnetism. Bifurcation of ZFC and FC 
      curve reveals the strong anisotropic nature. Astonishingly, magnetic measurements 
      show the non-zero magnetic moment aboveT(N)and broadening of the magnetic 
      transition indicates the presence of short-range uncompensated sublattice weak 
      ferromagnetic clusters in the paramagnetic region. The Mossbauer spectroscopy and 
      electron paramagnetic resonance studies exhibit the RT magnetically ordered 
      system and confirm the +3 state of Fe along with the fraction of Fe(2+)ions.
