Mesure precise de la susceptibilite magnetique de la phase icosaedrique pour une concentration en fer comprise entre 0 et 5. La reponse magnetique n'est pas completement independante de x. Pour de faibles concentrations, le fer augmente le moment mag

The now voluminous and often conflicting literature concerning the number and identification of the locations, valencies and spin quantum states adopted by iron when doped into the high- T c superconductor YBa 2 Cu 3 O y is analyzed. Although it now

Giant magnetoresistance in a spinodally decomposed, bulk 60 Cu‐20 Ni‐20 Fe alloy is reported. An annealed, quenched, and heat‐treated sample with a compositional modulation of ≲50 A size exhibits a ΔR/R value as high as 9% at 4.2 K. Optimiza

The Mossbauer effect has been used to measure the hyperfine field of 57Fe nuclei in the layered antiferromagnet Ba2FeF6. The temperature dependence of the sublattice magnetization was measured an order of magnitude closer to the Neel temperature than

A study of the Au197 Mossbauer resonance is reported as a function of oxygen stoichiometry for gold‐doped YBa2Cu3O7−δ. Three separate Mossbauer features are identified and correspond respectively to gold metal particles, Au3+ in a square‐plana

The Mossbauer effect of the 37.2 keV transition of 121Sb and the 23.88 keV γ transition of 119Sn has been employed to study the electronic configuration of Sb and Sn ions in the conducting materials BaSn1−xSbxO3 for 0≤x≤0.2. A single‐resonan

The Mossbauer effect of the 37.2 keV γ transition of 121Sb has been employed to study the electronic configuration of Sb ions in perovskite superconducting materials. The isomer shift (IS) changes with Sb content and falls in the region of the Sb(V)
