A combined deep inelastic neutron scattering andab initiolattice dynamics study of the hydride anion dynamics and bonding in La2LiHO3 oxyhydride
Fjellvåg, Øystein; Krzystyniak, Matthew; Vajeeston, Ponniah; Sjåstad, Anja Olafsen; Armstrong, Jeff (Peer reviewed; Journal article, 2019)Kobayashi et al (6279) (Science 2016, 351) reported recently the existence of pure H- conductivity in the oxyhydride La2−x−y Sr x+y LiH1−x+y O3−y , while demonstrating its functionality through a prototype solid-state ... -
Crystal structure of LaSr3Fe3O9 and its phase relation with LaSr3Fe3O10
Fjellvåg, Øystein; Øygarden, Vegar; Sørby, Magnus Helgerud; Sjåstad, Anja Olafsen (Peer reviewed; Journal article, 2019)The Ruddlesden-Popper phase LaSr3Fe3O10 and its reduced derivatives with nominal composition LaSr3Fe3O10–x, with 0 < x < 1.21, are described in detail with respect to crystal structure, magnetic order, thermal stability ... -
(De)sodiation Mechanism of Bi2MoO6 in Na-Ion Batteries Probed by Quasi-Simultaneous Operando PDF and XAS
Brennhagen, Anders; Skurtveit, Amalie; Wragg, David Stephen; Cavallo, Carmen; Sjåstad, Anja Olafsen; Koposov, Alexey; Fjellvåg, Helmer (Peer reviewed; Journal article, 2024) -
Effect of electron doping on the crystal structure and physical properties of an n = 3 Ruddlesden-Popper compound La4Ni3O10
Periyasamy, Manimuthu; Patra, Lokanath; Fjellvåg, Øystein; Ravindran, Ponniah; Sørby, Magnus Helgerud; Kumar, Susmit; Sjåstad, Anja Olafsen; Fjellvåg, Helmer (Peer reviewed; Journal article, 2021) -
Interplay of valence states and magnetic interactions in the perovskite system LaNi1–xRhxO3
Fjellvåg, Asbjørn Slagtern; Fjellvåg, Øystein; Kumar, Susmit; Ruud, Amund; Sjåstad, Anja Olafsen (Peer reviewed; Journal article, 2021)We report on the structural, magnetic and electronic properties of Rh substituted LaNiO3, LaNi1–xRhxO3 (0 ≤ x ≤ 1). Increased Rh contents are associated with increased structural distortion, and we observe a phase ... -

Nagell, Marius Uv; Kumar, Susmit; Sørby, Magnus Helgerud; Fjellvåg, Helmer; Sjåstad, Anja Olafsen (Journal article; Peer reviewed, 2015) -
Structural disorder and antiferromagnetism in LaNi1–xPtxO3
Fjellvåg, Asbjørn Slagtern; Fjellvåg, Øystein; Breard, Y.; Sjåstad, Anja Olafsen (Peer reviewed; Journal article, 2021) -
Unraveling the (De)sodiation Mechanisms of BiFeO<inf>3</inf> at a High Rate with Operando XRD
Brennhagen, Anders; Skautvedt, Casper; Cavallo, Carmen; Wragg, David Stephen; Koposov, Alexey; Sjåstad, Anja Olafsen; Fjellvåg, Helmer (Peer reviewed; Journal article, 2024)Development of new anode materials for Na-ion batteries strongly depends on a detailed understanding of their cycling mechanism. Due to instrumental limitations, the majority of mechanistic studies focus on operando ...
