“…This would mean that the difference in magnetization along a and b axis is not too strong. Lastly, in the case of ErVO 3 , in the work performed on its magnetic structure by Reehuis et al [39], they found that in the C-type magnetic structure, the spins were indeed on the ab plane, in agreement with our results.…”

“…Figure 6 shows the temperature dependence of these reflections for Pr 0.90 Ca 0.10 VO 3 . The reflections 100, 010, 102, and 012 exhibit a spontaneous increase in their magnetic intensity at the Néel temperature T N = 117(2) K, indicating the onset [17]. Our data analysis showed that the vanadium moments in Pr 0.90 Ca 0.10 VO 3 are aligned within the ab plane and that the C y component is the strongest.…”

“…Within the monoclinic phase at 15 K, the doping-induced reduction of the cell volume (3.1%) is similar to the value determined at 295 K, but the decrease of the b axis is larger than that of the c axis, indicating the presence of Jahn-Teller distortions of the VO 6 octahedra. Usually a change of the lattice parameters is strongly influenced by the ionic size and the valence of the R n+ ions, as shown earlier for rare-earth vanadates RVO 3 [15][16][17][18]. In the system Pr 1−x Ca x VO 3 , the influence of the ionic size effect at the R site should be negligible since the ionic radii of Pr 3+ and Ca 2+ are almost identical (see Ref.…”

“…In the present paper, we have performed single-crystal neutron diffraction experiments to investigate these transitions by measuring the temperature dependence of corresponding Bragg reflections. In earlier studies of insulating vanadates, the structural phase transition temperatures were extracted from intensity changes of strong nuclear Bragg reflections [3,[15][16][17]. Due to the spontaneous onset of orbital ordering, which is accompanied by Jahn-Teller distortions in the VO 6 octahedra, the crystal structure changes upon cooling from an orthorhombic to a monoclinic structure (see Sec.…”

“…The influence of the orbital degrees of freedom of the d electrons on the magnetic and transport properties of metal-oxide compounds has attracted much attention in recent years [1]. Mott-insulating orthovanadates of chemical composition RVO 3 (R = Y or a trivalent rare-earth metal) have been widely studied as a model system of the coupling between the spin and orbital degrees of freedom [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. The valence electrons on the V 3+ ions (electron configuration 3d…”

High-resolution powder x-ray diffraction and single-crystal neutron diffraction were used to investigate the crystal structure and magnetic ordering of the compound Pr 1−x Ca x VO 3 (0 x 0.3), which undergoes an insulator-to-metal transition for x ∼ 0.23. Since the ionic radii of Pr 3+ and Ca 2+ are almost identical and structural disorder is minimal, Pr 1−x Ca x VO 3 is a good model system for the influence of hole doping on the spin and orbital correlations in transition metal oxides. The end member PrVO 3 is a Mott-Hubbard insulator, which exhibits a structural phase transition at T S = 180 K from an orthorhombic to a monoclinic structure with space groups Pbnm and P 2 1 /b, respectively. This transition is associated with the onset of orbital ordering and strong Jahn-Teller distortions of the VO 6 octahedra. Antiferromagnetic C-type order with vanadium moments oriented in the ab plane is observed below T N = 140 K. Upon cooling, the vanadium moments induce a progressive magnetic polarization of the praseodymium sublattice, resulting in a ferrimagnetic structure with coexisting modes (C x , F y ) and (F x , C y ). In the insulating range of the Pr 1−x Ca x VO 3 phase diagram, Ca doping reduces both the orbital and magnetic transition temperatures so that T S = 108 K and T N = 95 K for x = 0.20. The Jahn-Teller distortions and ordered vanadium moments also decrease upon doping. In a metallic sample with x = 0.30, Jahn-Teller distortions and long-range orbital ordering are no longer observable, and the average crystal structure remains orthorhombic down to low temperature. However, broadening of some lattice Bragg reflections indicate a significant increase in lattice strain. Antiferromagnetic short-range order with a weak ordered moment of 0.14(3) μ B per vanadium atom could still be observed on the vanadium site below T ∼ 60 K. We discuss these observations in terms of doping-induced spin-orbital polaron formation.
