Effect of cation size variance on spin and orbital order in Eu${}_{1-x}$(La${}_{0.254}$Y${}_{0.746}$)${}_x$VO${}_3$

Abstract

We have investigated the $R$-ion ($R$ = rare earth or Y) size variance effect on spin/orbital order in Eu${}_{1-x}$(La${}_{0.254}$Y${}_{0.746}$)${}_x$VO${}_3$. 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.
