      abstract     = {We investigate the structural, magnetic, and specific heat
                      behavior of the hexagonal manganite Dy0.5Y0.5MnO3 in order
                      to understand the effect of dilution of Dy magnetism with
                      nonmagnetic yttrium. In this compound, the triangular Mn
                      lattice orders antiferromagnetic at T-N(Mn) approximate to
                      68 K observed experimentally in the derivative of magnetic
                      susceptibility as well as in specific heat. In addition, a
                      low-temperature peak at T-N(Dy) similar to 3 K is observed
                      in specific heat which is attributed to rare earth order.
                      The T-N(Mn) increases by 9 K compared to that of hexagonal
                      (h) DyMnO3 while T-N(Dy) is unchanged. A change in slope of
                      thermal evolution of lattice parameters is observed to occur
                      at temperature close to T-N(Mn). This hints at strong
                      magnetoelastic coupling in this geometric multiferroic. In
                      magnetization measurements, steplike features are observed
                      when the magnetic field is applied along the c axis which
                      shift to higher fields with temperature and vanish
                      completely above 40 K. The presence of different magnetic
                      phases at low temperature and strong magnetoelastic effects
                      can lead to such field-induced transitions which resemble
                      metamagnetic transitions. This indicates the possibility of
                      strong field-induced effects in dielectric properties of
                      this material, which is unexplored to date.},
