PrMn1.6Fe0.4Ge2 Alaşımının Curie Sıcaklığı Üzerindeki Antiferromanyetik Yapısı

Year 2005, Volume: 1 Issue: 26, 33 - 42, 01.06.2005

Abstract

ThCr2Si2-tipi kristal yapılı PrMn1.6Fe0.4Ge2 alaşımının manyetik özelliği ve manyetik yapısı zayıf alan mıknatıslanma ölçümü ve nötron toz kırınımı ile incelenmiştir. Düşük alan mıknatıslanma ölçümleri Curie sıcaklığının üzerinde antiferromagnetik düzenlenimin olduğunu göstermektedir. Bu antiferromagnetik düzenlenimin manyetik yapısı, Curie sıcaklığı = 230 K’ in üzerinde değişik sıcaklıklarda nötron toz kırınımı ile belirlenmiştir.

Antiferromagnetic Structure of the PrMn1.6Fe0.4Ge2 Compound above Curie Temperature

Abstract

The magnetic properties and structure of PrMn1.6Fe0.4Ge2 compound that crystallize in ThCr2Si2-type tetragonal structure (space group: I4/mmm) have been investigated by magnetic measurements and neutron diffraction experiments. The result of magnetic measurements in a weak external field shows that there is an antiferromagnetic ordering above Curie temperature. The magnetic structure of this antiferromagnetic ordering has been determined by powder neutron diffraction at the different temperature above Curie temperature T = 230 K.

Keywords

Selcuk University Journal of Science Faculty accepts articles in Turkish and English with original results in basic sciences and other applied sciences. The journal may also include compilations containing current innovations.

It was first published in 1981 as "S.Ü. Fen-Edebiyat Fakültesi Dergisi" and was published under this name until 1984 (Number 1-4).
In 1984, its name was changed to "S.Ü. Fen-Edeb. Fak. Fen Dergisi" and it was published under this name as of the 5th issue.
When the Faculty of Letters and Sciences was separated into the Faculty of Science and the Faculty of Letters with the decision of the Council of Ministers numbered 2008/4344 published in the Official Gazette dated 3 December 2008 and numbered 27073, it has been published as "Selcuk University Journal of Science Faculty" since 2009.
It has been scanned in DergiPark since 2016.
