    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 ...
  • Double Perovskite Cobaltites Integrated in a Monolithic and Noble Metal-Free Photoelectrochemical Device for Efficient Water Splitting 
    Zhu, Junjie; Guðjónsdóttir, Jónína; Strandbakke, Ragnar; Both, Kevin Gregor; Aarholt, Thomas; Almeida Carvalho, Patricia; Sørby, Magnus Helgerud; Jensen, Ingvild Julie Thue; Guzik, Matylda N.; Norby, Truls Eivind; Haug, Halvard; Chatzitakis, Athanasios Eleftherios (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    Water photoelectrolysis has the potential to produce renewable hydrogen fuel, therefore addressing the intermittent nature of sunlight. Herein, a monolithic, photovoltaic (PV)-assisted water electrolysis device of minimal ...
  • Electric and magnetic properties of Lanthanum Barium Cobaltite 
    Szpunar, Iga; Wachowski, Sebastian; Miruszewski, Tadeusz; Dzierzgowski, Kacper; Górnicka, Karolina; Klimczuk, Tomasz; Sørby, Magnus Helgerud; Balaguer, María; Serra, José M.; Strandbakke, Ragnar; Gazda, Maria; Mielewczyk-Gryń, Aleksandra (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)
    The cubic Ba0.5La0.5CoO3‐δ was synthesized using solid state reaction. The structural properties were determined by the simultaneous refinement of Synchrotron Powder X‐ray Diffraction and Neutron Powder Diffraction data. ...
  • High-Temperature Structural and Electrical Properties of BaLnCo2O6 Positrodes 
    Szpunar, Iga; Strandbakke, Ragnar; Sørby, Magnus Helgerud; Wachowski, Sebastian Lech; Balaguer, Maria; Tarach, Mateusz; Serra, José M.; Witkowska, Agnieszka; Dzik, Ewa; Norby, Truls Eivind; Gazda, Maria; Mielewczyk-Gryń, Aleksandra (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    The application of double perovskite cobaltites BaLnCo2O6−δ (Ln = lanthanide element) in electrochemical devices for energy conversion requires control of their properties at operating conditions. This work presents a study ...
  • MgH2–CoO: a conversion-type composite electrode for LiBH4-based all-solid-state lithium ion batteries 
    El-Kharbachi, Abdelouahab; Uesato, Hiroki; Kawai, Hironori; Wenner, Sigurd; Miyaoka, Hiroki; Sørby, Magnus Helgerud; Fjellvåg, Helmer; Ichikawa, Takayuki; Hauback, Bjørn (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    Several studies have demonstrated that MgH2 is a promising conversion-type anode toward Li. A major obstacle is the reversible capacity during cycling. Electrochemical co-existence of a mixed metal hydride-oxide conversion ...
  • Pseudo-ternary LiBH4-LiCl-P2S5 system as structurally disordered bulk electrolyte for all-solid-state lithium batteries 
    El-Kharbachi, Abdelouahab; Wind, Julia; Ruud, Amund; Høgset, Astrid Bygdås; Nygård, Magnus Moe; Zhang, Junxian; Sørby, Magnus Helgerud; Kim, Sangryun; Cuevas, Fermin; Orimo, Shin-Ichi; Fichtner, Maximilian; Latroche, Michel; Fjellvåg, Helmer; Hauback, Bjørn (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    The properties of the mixed system LiBH4–LiCl–P2S5 are studied with respect to all-solid-state batteries. The studied material undergoes an amorphization upon heating above 60 °C, accompanied with increased Li+ conductivity ...
  • Structural and magnetic aspects of La4(Co1-xNix)3O10+δ (0 ≤ x ≤ 1) 
    Nagell, Marius Uv; Kumar, Susmit; Sørby, Magnus Helgerud; Fjellvåg, Helmer; Sjåstad, Anja Olafsen (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2015)
    The Ruddlesden–Popper (RP3) type oxides, La4Co3O10+δ and La4Ni3O10+δ, form a complete solid solution. Powder X-ray and neutron diffraction data show that La4(Co1−xNix)3O10+δ is isostructural to the monoclinic La4Co3O10+δ ...
