Mossbauer study of α-Fe"2O"3 under ultra-high pressure
Utilizing the diamond anvil cell, the ^5^7Fe Mossbauer measurements under high pressure have been performed for α-Fe"2O"3 up to 72 GPa at room temperature. Mossbauer spectra above 50 GPa indicated the transition from the usual spin-flip hematite phase to the high pressure phase, which is c...

Mossbauer study of α-Fe"2O"3 under ultra-high pressure |
| abstract |
Utilizing the diamond anvil cell, the ^5^7Fe Mossbauer measurements under high pressure have been performed for α-Fe"2O"3 up to 72 GPa at room temperature. Mossbauer spectra above 50 GPa indicated the transition from the usual spin-flip hematite phase to the high pressure phase, which is characterized by the superimposition of the doublet and sextet in the Mossbauer spectrum, and coincided with the spectrum reported recently by Syono et al. The critical pressure of transformation to this phase was determined to be 52 GPa at room temperature by pressure distribution measurements using the ruby fine powder and laser microscopic systems. At the high pressure phase above 52 GPa the iron has at least two different kinds of electronic states at room temperature, which are shown as the doublet and sextet and a gradual transformation from the magnetically ordered state (sextet) to the paramagnetic state (doublet) occurred with an increase in pressure. |

Mossbauer spectra above 50 GPa indicated the transition from the usual spin-flip hematite phase to the high pressure phase, which is characterized by the superimposition of the doublet and sextet in the Mossbauer spectrum, and coincided with the spectrum reported recently by Syono et al. The critical pressure of transformation to this phase was determined to be 52 GPa at room temperature by pressure distribution measurements using the ruby fine powder and laser microscopic systems. At the high pressure phase above 52 GPa the iron has at least two different kinds of electronic states at room temperature, which are shown as the doublet and sextet and a gradual transformation from the magnetically ordered state (sextet) to the paramagnetic state (doublet) occurred with an increase in pressure.</subfield></datafield><datafield tag="533" ind1=" " ind2=" "><subfield code="f">Elsevier Journal Backfiles on ScienceDirect 1907 - 2002</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Kurimoto, K.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Nasu, S.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Nagatomo, S.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Endo, S.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Fujita, F.E.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">in</subfield><subfield code="t">Physica B+C</subfield><subfield code="d">Amsterdam : Elsevier</subfield><subfield code="g">139-140(1986), Seite 495-498</subfield><subfield code="w">(DE-627)NLEJ177412429</subfield><subfield code="w">(DE-600)2208195-1</subfield><subfield code="x">0378-4363</subfield><subfield code="7">nnns</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:139-140</subfield><subfield code="g">year:1986</subfield><subfield code="g">pages:495-498</subfield></datafield><datafield tag="856" ind1="4" ind2="0"><subfield code="u">http://linkinghub.elsevier.com/retrieve/pii/0378-4363(86)90631-5</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_USEFLAG_H</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">ZDB-1-SDJ</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_NL_ARTICLE</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">139-140</subfield><subfield code="j">1986</subfield><subfield code="h">495-498</subfield></datafield></record></collection>
