Refinement on F resulted in R=1.9%. The structure is comprised of a network of corners, edges and faces sharing the coordination polyhedra of neodymium. In between this skeleton the regular octahedra of oxygen-coordinated iron and trigonal prisms of lithium are located. The Mössbauer spectra revealed the presence of ▫$Fe^3+$▫, ▫$Fe^4+$▫ and ▫$Fe^5+$▫ ions distributed on two symmetry-independent lattice positions.20072012-06-01 11:15:00Neznano27442UDK: 548.73COBISS_ID: 10850838ISSN pri članku: 0022-4596NUK URN: URN:SI:UM:DK:C1HYB2UYsl
