We find that, as a consequence of this, the magnetic transition is close to (and even above) the superexchange driven orbital-ordering transition, whereas typically magnetism arises at much lower temperatures than orbital ordering. Our results support the experimental scenario of orbital ordering and G-type spin correlations just above the monoclinic-to-orthorhombic structural change. To explore the effects of crystal-field splitting and filling, we compare to $YVO_3$ and $t^1_2g$ titanates. In all these materials the crystal field is sufficiently large to suppress the Kugel’-Khomskii phase transition.}, cin = {IAS-3 / JSC}, ddc = {530}, cid = {I:(DE-Juel1)IAS-3-20090406 / I:(DE-Juel1)JSC-20090406}, pnm = {5215 - Towards Quantum and Neuromorphic Computing Functionalities (POF4-521) / 5111 - Domain-Specific Simulation $\&$ Data Life Cycle Labs (SDLs) and Research Groups (POF4-511)}, pid = {G:(DE-HGF)POF4-5215 / G:(DE-HGF)POF4-5111}, typ = {PUB:(DE-HGF)16}, UT = {WOS:000859707800004}, doi = {10.1103/PhysRevB.106.115110}, url = {https://juser.fz-juelich.de/record/910612}, }
