Magnetic behavior ofCeFe2: Effects of Ru, Rh, and Pd substitutions

Magnetism in gallium-dopedCeFe2: Martensitic scenario

“…Stabilization of the AFM phase in CeFe 2 has been reported earlier with Co, Al, Ru, Ir, Os, and Re doping. 3,[5][6][7] Another effect of Ga substitution is the gradual decrease in T C . Figure 2͑b͒ shows the typical field variation in the M-T plots for the compound with x = 0.025.…”

“…1 It has been reported that substitution of small amounts of elements such as Co, Al, Ru, Ir, Os, and Re stabilizes the low-temperature dynamic AFM phase in CeFe 2 . 3,[5][6][7] The coexistence of FM and AFM phases across the AFM-FM transition in the case of Ru-doped CeFe 2 has been shown by Hall probe imaging, and this transition bears distinct signatures of first-order phase transition, namely, supercooling, superheating, and time relaxation. 8 Very sharp magnetization step across the fieldinduced AFM-FM transition has been reported at temperatures less than 5 K when CeFe 2 is doped with Ru and Re.…”

Pressure tuning of competing magnetic interactions in intermetallic CeFe2

“…[15]), and Ce(Fe 1−x Ru x ) 2 (Ref. [18]). No lattice constant data for Ce(Fe 1−x Ir x ) 2 is available so we used Vegard's law to interpolate between CeFe 2 and CeIr 2 (Ref.…”

“…There exists extensive literature on chemically doped CeFe 2 , with numerous choices of dopants replacing either Ce, or Fe, or both [15][16][17][18][19][20][21][22] . The ferromagnetic ground state of CeFe 2 undergoes a phase transition to an antiferromagnet with small amounts of chemical doping on the Fe site by one of many elements including Al, Co, Ru and Ir [15][16][17][18][19][20][21][22] .…”

“…The ferromagnetic ground state of CeFe 2 undergoes a phase transition to an antiferromagnet with small amounts of chemical doping on the Fe site by one of many elements including Al, Co, Ru and Ir [15][16][17][18][19][20][21][22] . Previous work on stoichiometric CeFe 2 found evidence for a new phase at high pressure which, by comparison with the doped systems, was suggested to be the antiferromagnetic phase [23][24][25] .…”
