Magnetic and transport properties of vanadate PrVO₃

Abstract

The magnetic and electric properties of the vanadate PrVO3 with the GdFeO3 -type orthorhombic structure are reported. The temperature-dependent magnetization displays an obvious irreversibility under zero-field cooling (ZFC) and field cooling (FC), and two magnetic phase-transition temperatures 20 K and 90 K, which may correspond to the spin reorientation and the magnetic ordering, respectively. A canted antiferromagnetic configuration is derived from the low spontaneous magnetization at 5 K. In the sintered bulk, a high coercivity 2.4 T is due to the pinning of the domain wall. The resistance measurement shows that the compound is an insulator at low temperatures.

Magnetism tailored by mechanical strain engineering in PrVO3 thin films

“…On LSAT and LAO substrates, both parameters are influenced : the strain being compressive, the PVO in-plane lattice parameter is decreased to fit the one of the substrate, , a hard ferromagnetic behavior was also reported for bulk PVO in Ref. [32,33]. This discrepancy of coercivity between bulk and PVO films could be explained by the microstructure.…”

Insulator-to-metal transition in(R,Ca)VO3

“…[23][24][25] We found that the IM transition had little effect on the structural properties; details can be found elsewhere. 26 All three series of doped materials exhibit AF ordering that persists in the ground state beyond the critical doping level x c for the IM transition.…”

Bulk modulus and thermal properties of RVO3 (R=La, Ce, Pr, Nd)

“…[1,[5][6][7][8]15,[22][23][24] for RVO 3 (R = La, Ce, Pr, Nd) and this data is used for the evaluation of model parameters (b 1 , 1 ) and (b 2 , 2 ) using Eqs. (4) and (5).…”

“…The purpose of this paper is to provide a complete basis for the theoretical description of the elastic and thermal properties of the vanadates. At room temperature these materials exhibit the orthorhombic GdFeO 3 -type structure with space group Pbnm [6][7][8][9][10][11][12][13][14][15] resulting from a cooperative distortion of the VO 6 octahedra. The temperature driven structural phase transition from an orthorhombic to a monoclinic structure, with space groups Pbnm and P2 1 /b11, respectively [7][8][9], motivates to probe the lattice dynamics associated with these structural changes.…”

“…LaVO 3 the first compound of the series exhibits many exciting properties which can be related to orbital and spin rearrangements [15]. It has been studied extensively in terms of its structural changes but there still exist a number of issues which have yet to be resolved [3].…”
