  • Enhancement of ferromagnetism by Co and Ni substitution in the perovskite LaBiMn2O6+d 
    Kundu, Asish K; Pralong, V; Caignaert, V; Rao, C N R; Raveau, B (Royal Society Chemistry, 2007)
    The substitution of cobalt and nickel for manganese in the perovskite manganate LaBiMn2O6+delta. has been realized, leading to the perovskites LaBiMn2-MxO6+delta, with M = Co, Ni and 0 <= x <= 2/3. In contrast to the ...
  • Temperature-induced magnetization reversal in BiFe0.5Mn0.5O3 synthesized at high pressure 
    Mandal, P; Sundaresan, A; Rao, C N R; Iyo, A; Shirage, P M; Tanaka, Y; Simon, Ch; Pralong, V; Lebedev, O I; Caignaert, V; Raveau, B (The American Physical Society, 2010-09-28)
    BiFe0.5Mn0.5O3 could be stabilized in the perovskite structure by preparing it under high pressure and temperature. It has an orthorhombic structure with a possible ordered arrangement of Fe and Mn double rows and shows a ...
  • Zero magnetization in a disordered (La1−x/2Bix/2)(Fe0.5Cr0.5)O3 uncompensated weak ferromagnet 
    Vijayanandhini, K; Simon, Ch; Pralong, V; Breard, Y; Caignaert, V; Raveau, B; Mandal, P; Sundaresan, A; Rao, C N R (IOP Publishing Ltd, 2009-12-02)
    The orthorhombic perovskite, (La1-x/2Bix/2)(Fe0.5Cr0.5)O-3 was investigated for 0 <= x <= 1. Its space group, Pnma, compatible with the disordering of iron and chromium in the B sites, confirms previous observations. More ...
