      abstract     = {Sm$_2$Ti$_{2−x}$V$_x$O$_7$, a member of the rare-earth
                      titanate pyrochlores, exhibits dipolar-octupolar
                      antiferromagnetism below 𝑇$_𝑁$=0.35K. We observed two
                      ferroelectric transitions at 182 (𝑇$_{FE1}$) and 52 K
                      (𝑇$_{FE2}$), significantly higher than 𝑇$_𝑁$ for
                      Sm$_2$⁢Ti$_{2−𝑥}$⁢V$_𝑥$⁢O$_7$ (𝑥=0,0.1).
                      Although the ferroelectric transition temperatures remain
                      unchanged, the polarization value decreases with V doping. A
                      structural transition to a polar 𝑅⁢3⁢𝑚
                      rhombohedral phase from the cubic
                      𝐹⁡𝑑⁢$\bar{3}$𝑚 structure occurs at 𝑇$_{FE1}$
                      for the pristine compound, involving a distortion in the
                      pyrochlore lattices formed by the Sm atoms. Remarkably,
                      linear magnetoelectric coupling is observed in both
                      compounds, with further enhancement of magnetoelectric (ME)
                      coupling due to magnetic V doping. The existence of
                      magnetoelectric coupling without long-range magnetic order
                      is of fundamental interest for advancing the understanding
                      and development of ME coupling.},
