Investigation of the crystal structure and magnetic properties of Nd1−Gd Mn2Si2 compounds

Magnetic characterization of LaMn 2–x Co x Ge 2 compounds

“…This reordering at T SR is probably due to change in the easy axis direction from the c-axis to the basal plane with decreasing temperature. Similar feature was observed in NdMn 2-x Cr x Si 2 [13] and Nd 1-x Gd x Mn 2 Si 2 [14] compounds. The Curie temperature T C (Mn) was depressed linearly by the substitution of Co for Mn.…”

Structural and magnetic properties of Gd1−xPrxMn2Si2 silicides

“…Increase of these parameters may be associated with the smaller atomic radius of Gd compared with Pr. The lattice parameters for x = 0 and x = 1 are in good agreement previously reported values in the literature [19][20][21]. All d a…”

“…This may be associated with increase of the unit cell volume V with increasing Pr content x. Increases of the unit cell volume weaken interlayer antiferromagnetic Mn-Mn interactions, resulting in decreases of the Néel temperature T N (Mn) [21]. The Curie temperature T C (Gd) becomes depressed linearly and disappears with increasing Pr content.…”

“…GdMn 2 Si 2 and PrMn 2 Si 2 compounds are antiferromagnetic below T N (Mn) = 472 and 348 K, respectively. The magnetic moment of the Gd sublattice in GdMn 2 Si 2 becomes ordered and antiferromagnetically coupled with the magnetic moment the Mn sublattice below 61 K, while the magnetic moment of the Pr sublattice in PrMn 2 Si 2 is not ordered at low temperatures [15][16][17]21].…”

“…The magnetic properties of RMn 2 Si 2 compounds were studied before [14][15][16][17][18][19][20][21]. All RMn 2 Si 2 compounds except LaMn 2 Si 2 show antiferromagnetic behavior.…”
