  • Low to High Spin-State Transition Induced by Charge Ordering in Antiferrimagnetic YBaCo2O5 
    Vogt, Tom; Woodward, Patrick M.; Karen, Pavel; Hunter, B.A.; Henning, P.; Moodenbaugh, A.R. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2000)
    The oxygen-deficient double perovskite YBaCo 2 O 5 , containing corner-linked CoO 5 square pyramids as principal building units, undergoes a paramagnetic to antiferromagnetic spin ordering at 330 K. This is accompanied ...
  • Verwey transition in mixed-valence TbBaFe2O5: Two attempts to order charges 
    Karen, Pavel; Woodward, Patrick M.; Lindén, Johan; Vogt, Tom; Studer, Andrew; Fischer, Peter (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2001)
    Electronic, magnetic, and structural phase transitions in nearly stoichiometric TbBaFe 2 O 5 + w ( 0.00 < w < 0.05 ) have been investigated. At high temperatures this compound is a paramagnetic, mixed-valence (Fe 2 . 5 + ...
