Magnetic structure of Tb2CuIn3

The magnetic states of Gd2CuIn3

“…The initial frequency shift dT SG was estimated from the relation: dT SG ¼ DT SG =ðT SG D log oÞ and it was found that dT SG $0:0536 AE 0:0004. This result is very near to that observed in the SG system (LaGd) Al 2 (0.06) [22] or the NMAD isostructurals Tb 2 CuIn 3 (0.06) [14], Tb 2 PdSi 3 (0.046) and Dy 2 PdSi 3 (0.044) [23]. However, it is considerably higher than the frequency shift observed in the canonical SG systems of Ce 2 AgIn 3 ($0.022) [2] or the SG with short-range AF order isostructural Nd 2 AgIn 3 ($0.015) [1].…”

“…The magnetic properties of the ternary intermetallic systems R 2 TX 3 , where R ¼ rare earth, T ¼ Pd, Cu, Ag and X ¼ Ga, Ge or In have been intensively investigated macroscopically utilizing AC-DC susceptibility and magnetization measurements as well as microscopically by neutron diffraction [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. Structurally, they crystallize in either the AlB 2 or its deformed hexagonal derivative CaIn 2 -type structure (space groups P6/mmm and P6 3 /mmc, respectively), thus forming a layered structure along the c-axis, consisting of two-dimensional triangular rare earth (R) planes separated by sheets of mixed, nonmagnetic (T-X) elements.…”

“…Furthermore neutron diffraction on the ordered Tb 2 CuX 3 phases [11,[14][15][16][17] at low temperatures reveals a strong dependence of the crystalline electric field (CEF) upon replacing the Ge with In ions (see Ref. [17]).…”

Structure of TbAg0.46In1.54 from single crystal data

“…The crystal structure and magnetic properties of the ternary copper indides RE 2 CuIn 3 (RE = Ce, Pr, Nd, Sm, Gd) with the CaIn 2 structure type were described by Tyvanchuk et al [7]. The crystal and magnetic structures of the Tb 2 CuIn 3 intermetallic compound (CaIn 2 -type) have been studied by neutron diffraction in the temperature range 3.8 to 293 K [8].…”

Extended short-range ferromagnetic order with cluster-glass behavior in Dy2AuSi3

“…Many of the R 2 TX 3 compounds crystallize in an AlB 2 -derived hexagonal structure (space group P6/mmm), which consist of R and M-X layers alternating along the c-axis, and the possible crystallographic disorder within M-X positions. These intermetallics exhibit a variety of interesting magnetic properties such as ferromagnetic (FM) ordering in Nd 2 PdSi 3 [3], antiferromagnetic (AFM) ordering in Tb 2 RhSi 3 [4], spin-glass (SG) behavior in U 2 PdSi 3 [5] and Ce 2 AgIn 3 [6], and coexistence of SG state and long-range magnetic order in Dy 2 PdSi 3 [7], Tb 2 PdSi 3 [3,7] and Tb 2 CuIn 3 [8]. A common feature observed for these compounds is the presence of metastable magnetic ground state even for the long-range FM or AFM ordering systems characterized predominantly with the evident difference between field cooling (FC) and zero-field cooling (ZFC) dc susceptibility and long time magnetic relaxation behavior.…”
