Nakamura, J; Karppinen, M; Karen, Pavel; Linden, J; Yamauchi, H (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2004)Two types of chemical-pressure effects on the Verwey-type transition in Ba Sm Fe 2 O 5 are studied, viz., ionic-size contractions at the Ba and Sm sites. Whereas the replacement of Sm by the smaller Eu and Gd atoms increases ...

Linden, J; Lindroos, F.; Karen, Pavel (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Thermal evolution of the Fe2+–Fe3+ valence mixing in YBaFe2O5 is investigated using Mössbauer spectroscopy. In this high-spin double-cell perovskite, the d6 and d5 Fe states differ by the single minority-spin electron which ...

Linden, J; Karen, Pavel; Nakamura, J; Karppinen, M; Yamauchi, H (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2006)Magnetoresistance, electrical transport, and magnetic properties associated with a two-step Verwey-type transition in BaGdFe 2 O 5 + w (− 0.015 < w < 0.181 ) are studied as a function of temperature and oxygen nonstoichiometry ...
