A magnetic study of TiNiSi-type GdMn1−xTixGe alloys

X-ray phase analysis and metallographic analysis were employed in investigations of the crystal structure of GdMn1-xTixGe (x = 0; 0.05; 0.1; 0.2) solid solutions. It is found that these new compounds crystallize in the orthorhombic TiNiSi-type structure. The magnetic properties of these solid soluti...

Summary:X-ray phase analysis and metallographic analysis were employed in investigations of the crystal structure of GdMn1-xTixGe (x = 0; 0.05; 0.1; 0.2) solid solutions. It is found that these new compounds crystallize in the orthorhombic TiNiSi-type structure. The magnetic properties of these solid solutions have been studied by magnetization and susceptibility measurements. All investigated compounds exhibit magnetic ordering of antiferromagnetic or ferromagnetic type. It was discovered that an increase of Ti content in the GdMn1-xTixGe samples leads to the appearance of ferromagnetic moment in these compounds and changes their magnetic ordering. The magnetic behavior of GdMn1-xTixGe is correlated with changes in Mn-Mn, Mn-Ge, and R-Mn distances.
