Antiferromagnetism and mass-enhanced behavior in Ce2CuSi3

Structure and physical properties of RE2AgGe3 (RE=Ce, Pr, Nd) compounds

“…Here we give a brief overview on the compounds based on Ce, Nd and Pr. The examples are atom-disorder spin glass behavior was observed in Ce 2 CuSi 3 , Pr 2 CuSi 3 , Nd 2 CuSi 3 ; Kondo lattice compound Ce 2 NiGe 3 showed spin glass behavior; short range antiferromagnetic ordering was observed in Nd 2 NiGe 3 ; annealed sample of Ce 2 NiSi 3 showed antiferromagnetic transition at 4.2 K and additional anomaly at 2.5 K, Ce 2 FeSi 3 and Ce 2 PdSi 3 exhibit Kondo behavior and ferromagnetic ordering was observed below 16 K in Nd 2 PdSi 3 [12][13][14][15][16][17][18][19], Kondo lattice reported in Ce 2 IrSi 3 and Ce 2 CoSi 3 [20,21]; weak spin glass behavior was observed in Nd 2 PtSi 3 [22]. Ce 2 RhSi 3 is antiferromagnetic below T N o7 K, ferromagnetic spiral magnetic ordering was observed at 4.2 K observed in a Nd 2 RhSi 3 [21,23] and Ce 2 CuGe 3 was reported as to show spin glass behavior [24].…”

Magnetic behavior ofEu2CuSi3:Large negative magnetoresistance above the Curie temperature

“…The investigation of Eu 2 CuSi 3 , crystallizing in an AlB 2 -type hexagonal structure has been undertaken considering current interest in synthesizing and investigating magnetic properties of ternary rare-earth/actinide compounds with the atomic ratios of 2:1:3, particularly those adopting variants of either the tetragonal ThSi 2 or hexagonal AlB 2 structure types. 4,5,[12][13][14][15][16][17][18][19][20][21][22][23] It is to be noted that the reports on Eu compounds of this type are generally rare. Recently, we reported the synthesis and interesting magnetic behavior of the compound, Eu 2 PdSi 3 [Ref.…”

La substitution induced linear temperature dependence of electrical resistivity and Kondo behavior in the alloys, Ce2−xLaxCoSi3

“…The ternary rare-earth (R) compounds of the type, R 2 TX 3 (T= transition metals, X= Si, Ga), derived from AlB 2 -type hexagonal structure have attracted considerable attention in the recent past [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. Perhaps this class of rare-earth intermetallics will be one of the most extensively studied ones next to ThCr 2 Si 2 -type structure.…”
