XRD pattern of , indexed in a cubic unit cell with parameter .
Comparison of the observed (crosses), calculated (solid line), and difference (at the bottom) NPD patterns. (a) . The two series of tick marks correspond to the positions of the allowed Bragg reflections for the main phase and vanadium. (b) . The third series of tick marks corresponds to the magnetic reflections.
Thermal evolution of the FC and ZFC dc susceptibility. Upper inset: reciprocal susceptibility (FC data).
Magnetization vs magnetic field isotherms at , 10, and 30 K.
Thermal evolution of the real an imaginary part of the ac susceptiblity.
Thermal evolution of the NPD patterns measured at 2, 10, 50, and 300 K.
