Incommensurate (IC) charge-order (CO) and spin density wave (SDW) order inelectron doped SrMn1-xWxO3-{\delta} (x= 0.08 to 0.1875) have been studied usingneutron diffraction.The study highlights the drastic effect of electron dopingon the emergence of magnetic ground states which were not revealed inmanganites before. With increasing (x) the crystal structure changes fromsimple tetragonal (P4/mmm) to an IC-CO modulated structure with superspace-group P2/m({\alpha}\b{eta}0)00 having ab-planer ferro order of 3dx2-y2orbitals in a compressed tetragonal (c<a) lattice. The IC-CO order is found tobe intimately related with the 3dx2-y2 orbital order.The occurrence of IC-COhas been attributed to the mixed character (itinerant/localized) ofeg-electrons undergoing Fermi-surface nesting of 3dx2-y2 band causingelectronic instability, which opens a gap through a charge density wave (CDW)mechanism. This feature appears to share proximity with the high-Tc cuprates.At lower temperatures, the CDW phase undergoes SDW transition, which changescontinuously with x and finally disappear at higher x due to the introductionof large frustration into the system. For 0.08 < x < 0.10 a C-typeantiferromagnetic (AFM) order with propagation vector k = (1/2, 1/2, 0) appearsunder ferro-ordering of 3dz2 orbitals, whereas for x > 0.1, a different C-typeAFM order with propagation vector k = (1/2,0,1/2), coexists with anincommensurate SDW order with k = (0.12, 0.38, 1/2).For compositions with0.1625 < x < 0.175, while the structural features of CDW and orbital-orderremain qualitatively the same, the magnetic interaction gets modified andresults another SDW phase with single incommensurate propagation vector k =(0.07, 0.43, 1/2). A detail magnetic and structural phase-diagram, as afunction of W substitution for SrMn1-xWxO3 (0.08 < x < 0.4) is presented.
