“…If an element substitutes for Fe, its position in the crystallographic structure will be largely determined by the atomic environment and the volume of the site. For example, Mo, V, and Ti atoms preferentially occupy the 8i sites, while Si and Co atoms preferentially occupy the 8j and 8f sites [1,[17][18][19][24][25][26] . These preferences are determined by both size effects and enthalpy effects.…”

A series of Nd 1−y Dy y Fe 11−x TiM x (M = Mo, Si) alloys have been prepared by arc melting and studied by X-ray diffraction and neutron diffraction. All samples are found to crystallize in the ThMn 12 -type structure. The lattice parameters a and c and unit cell volume V of Nd 0.5 Dy 0.5 Fe 11−x TiMo x alloys increase linearly with increasing content of Mo (x), while the lattice parameters a and c and unit cell volume V of Nd 0.5 Dy 0.5 Fe 11−x TiSi x alloys decrease linearly with increasing content of Si(x). In Nd y Dy 1−y Fe 11−x TiM x (M = Mo, Si) compounds, Ti and Mo atoms preferentially occupy the 8i sites and Si atoms preferentially occupy the 8j and 8f sites. Magnetic measurements show that the substitution of Fe by either Mo or Si leads to a decrease in the Curie temperature.rare earth-transition metal compounds, crystal structure, X-ray diffraction, neutron diffraction

“…Magnetic properties of RFe 11 Ti compounds with ThMn 12 structure were described more then 20 years ago [4,5]. Nevertheless a number of works show discrepancies in the temperatures and even in the type of magnetic reorientation transitions [6][7][8]. Recently it was shown that these compounds can exist for different compositions with the same type of crystal structure [8][9][10][11][12].…”

A comparative analysis of the magnetic properties of RFe11Ti and RFe9Ti single crystals (R=Ho,Er) with ThMn12 structure was carried out. It is shown that the decrease of iron content causes a 10% decrease in the saturation magnetization and a reduction by 10-15K in the Curie temperature. Besides, field induced spin reorientation appears at about 60 kOe in RFe9Ti, while in HoFe9Ti the First Order Magnetization Process transition field increases by 10 kOe with respect to the corresponding RFe11Ti compound.

“…Nevertheless, there are many reasons why the quantitative analysis of magnetic properties from domain structure can be erroneous. It is known that the magnetoelastic contribution can change the magnetic anisotropy type of the sample surface layer in comparison with the anisotropy of the sample volume [3,4]. In this work the results of experimental study of the magnetic domain structure of the DyFe11Ti compound, as well the analysis of the mechanical stress influence on the surface DS of bulk crystals are presented.…”

“…Besides, DyFe 11 Ti compound possess the large magnetostriction [11]. Temperature study of the magnetic DS of DyFe 11 Ti single crystals was carried out in [3,4], where it was shown by means of magnetic measurements that two SRT occurred in the sample (T srt1 =275 K and T srt2 =125 K), and at the same time two types of areas with different SRT temperatures were observed by means of DS study. The presence of impurities of the second phase can be excluded since the studies were carried out on single crystals.…”

Abstract. In this work, we present the results of the DyFe11Ti compound magnetic domain structure (DS) exploration. It was found that mechanical polishing leads to a change of the anisotropy of the surface layer, which affects the magnetic DS configuration. It is established that the equilibrium structure of the surface domains is restored through time under unchanged external conditions. It is suggested that the mechanism of DS relaxation has thermal fluctuation nature.
