Hysteretic "Magnetic-Transport-Structural" Transition in "114" Cobaltites: Size Mismatch Effect
Tapati Sarkar, V. Caignaert, V. Pralong +1
The triple "magnetic-transport-structural" transition versus temperature in three series of "114" cobaltites - Y1-xYbxBaCo4O7, Y1-xCaxBaCo4O7 and Yb1-xCaxBaCo4O7 - has been studied…

Competition between Ferrimagnetism and Magnetic Frustration in Zinc Substituted YBaFe4O7
Tapati Sarkar, V. Pralong, V. Caignaert +1
The substitution of zinc for iron in YBaFe4O7 has allowed the oxide series YBaFe4-xZnxO7, with 0.40 < x < 1.50, belonging to the "114" structural family to be synthesized. These ox…
