Topochemical fluorination of some Ruddlesden-Popper phases
This thesis describes the synthesis and the characterization of some n = 2 Ruddlesden-Popper oxide phases (A3B2O7; A = La, Y, Sr or Ca; B = Cr, Ni or Mn) and their topochemically fluorinated phases.
La2SrCr2O7 adopts an A2/a (a-a-c-/a-a-c-) distorted structure with antiferromagnetic order below TN ~ 260 K. DFT calculations performed on La2SrCr2...Expand abstract
