Investigation of the crystal properties of RFe2Si2 and RFe2Ge2 by X-ray diffraction and mössbauer spectroscopy

Magnetocaloric properties in the PrFe2Ge2 antiferromgnet

“…139) as reported before [14,16]. Within the margin of experimental error, the lattice parameters a and c are determined to be 4.063 and 10.542 Å respectively, which are in a good agreement with the published results in [14] and [16]. 14.5 K can be clearly seen in both ZFC and FC branchs, which is considered to be a feature of AFM-PM transition.…”

“…It reveals that all the peaks can be indexed according to the PDF data base (PDF#65-5579), and thus the sample is determined to crystallize in a pure phase tetragonal ThCr 2 Si 2 -type structure (space group: I4/mmm, No. 139) as reported before [14,16]. Within the margin of experimental error, the lattice parameters a and c are determined to be 4.063 and 10.542 Å respectively, which are in a good agreement with the published results in [14] and [16].…”

Magnetic properties of DyFe2Si2 studied with a two‐ion model for rare‐earth antiferromagnets

“…A powder neutron-diffraction experiment [2] revealed that the Dy moments are sine modulated with a propagation vector k = (0.335, 0, 0.136) below the Néel temperature N T (= 3.8 K). No magnetic moment was detected on the Fe sites as confirmed by 57 Fe and 161 Dy Mössbauer spectroscopy [3][4][5].…”

Evidence for proximity ofYFe2Si2to a magnetic quantum critical point

“…However, while there is no magnetic ordering, there a significant variation in the reported magnetic properties perhaps due to sample * singhdj@missouri.edu differences. [24][25][26][27][28][29][30][31][32] …”
