Competing ferro- and antiferromagnetism in R2CuIn3 (R=Tb,Ho,Er) intermetallics studied by neutron diffraction and magnetization measurements

The magnetic states of Gd2CuIn3

“…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]).…”

Magnetism of frustrated R2TIn3compounds (R = Nd, Ho, Er; T = Ag,Cu) by muon spin rotation

“…are details of the stacking sequence. The crystal structures do not change between room temperature and 4 K, although the unit cell gets smaller by ∼10% [1,2]. The lattice parameters (a, c) decrease slightly with increasing Z (by about 4% between Nd 2 AgIn 3 and Er 2 AgIn 3 ) without any particular irregularity.…”

Structures and physical properties ofR2TX3compounds

“…The system of R 2 T X 3 has become the subject of intensive studies. Inside the system, there are respective families categorized as R 2 NiGe 3 , [18] R 2 PdSi 3 , [19][20][21][22][23][24] R 2 RhSi 3 , [25,26] R 2 AgIn 3 , [27,28] R 2 CuIn 3 , [29][30][31] etc. Each family usually presents almost similar properties.…”
