Abstract

We have investigated the R-ion (R = rare earth or Y) size variance effect on spin/orbital order in Eu_1-x(La_0.254Y _0.746)_xVO₃. The size variance disturbs one-dimensional orbital correlation in C-type spin/G-type orbital ordered states and suppresses this spin/orbital order. In contrast, it stabilizes the other spin/orbital order. The results of neutron and resonant x-ray scattering denote that in the other ordered phase, the spin/orbital patterns are G type/C type, respectively.
