Magnetism and archaeology: Magnetic oxides in the first American civilization
(Elsevier, 1977)
Archaeological excavations at sites of the Olmec civilization (1500 to 500 B.C. in present-day Mexico) have unearthed artifacts formed from massive iron oxide ores. Iron oxide ores were ground and shaped into highly polished ...
Investigation of Virgin Coals and Coals Subjected to a Mild Acid Treatment
(Kluwer Academic Publishers; Springer Science+Business Media, 1998-03)
A quantitative determination of the relative marcasite/pyrite contents in virgin coals is possible by means of 57 Fe Mössbauer spectroscopy. Complications arise, however, when iron-containing silicates, carbonates, or other ...
Collective electron states in ZnxFe3-xO4 and CdxFe3-xO4 for 0 [les] x [les] 0.3
(Elsevier, 1977)
57Fe Mossbauer measurements of ZnxFe3-xO4 and CdxFe3-xO4 have been made at 300 K in zero applied field and at 180 K in zero and 55 kG applied fields. The compositional dependence of the isomer shifts, B to A area ratios ...
Structure-property relationships in the R-type hexaferrites: Cation distributions and magnetic susceptibilities of MX 2 Fe 4 O 11
(Baltzer Science Publishers, Baarn/Kluwer Academic Publishers; J. C. Baltzer AG, Science Publishers ; Springer Science+Business Media, 1994-12)
The strong, and heretofore unexplained, dependence of the magnetic properties of the R-type hexaferrites MX 2 Fe 4 O 11 on heat treatment has been investigated by means of 57 Fe and 119 Sn Mössbauer spectroscopy at 297 K. ...
Giant hyperfine field at the antimony site in the Heusler-alloy Pd2MnSb
(Elsevier, 1972-03-27)
The magnetic hyperfine field at 121Sb in Pd2MnSb has the anomalously large value (at 100 K) of +/-579 +/-5 kG. In the closely related compound PdMnSb we find +/-302 +/-5 kG, similar to other ferromagnetic intermetallics ...
57 Fe Mössbauer investigations of manganese-containing spinels
(Baltzer Science Publishers, Baarn/Kluwer Academic Publishers; Baltzer Science Publishing BV ; Springer Science+Business Media, 1994-12)
Cation distributions and related order-disorder phenomena in the naturally occurring Mn-spinels: iwakiite, galaxite and franklinite, have been investigated by means of 57 Fe Mössbauer spectroscopy. Previous measurements ...
