      abstract     = {We have carried out a systematic study on the effect of Cu
                      doping on nuclear, magnetic, and dielectric properties in
                      Mn1−xCuxWO4 for 0≤x≤0.19 by a synergic use of
                      different techniques, viz, heat capacity, magnetization,
                      dielectric, and neutron powder diffraction measurements. Via
                      heat capacity and magnetization measurements we show that
                      with increasing Cu concentration magnetic frustration
                      decreases, which leads to the stabilization of commensurate
                      magnetic ordering. This was further verified by
                      temperature-dependent unit cell volume changes derived from
                      neutron diffraction measurements which was modeled by the
                      Grüneisen approximation. Dielectric measurements show a low
                      temperature phase transition below about 9–10 K.
                      Furthermore, magnetic refinements reveal no changes below
                      this transition indicating a possible spin-flop transition
                      which is unique to the Cu doped system. From these combined
                      studies we have constructed a magnetoelectric phase diagram
                      of this compound.},
