“…8 The resulting model shows an AF ground state with a noncollinear magnetic structure on the Fe sublattice which breaks the frustrated AF configuration of the cubic lattice, inducing a rhombohedral lattice distortion, as found in REFe 2 ͑RE= Tb, Er, Ho, and Tm͒ compounds which develop giant spontaneous magnetostriction. 9 The proposed longrange noncollinear structure in the low temperature AF phase rationalizes many of the unusual and conflicting experimental results, as reported in the literature for this material, [10][11][12] and can explain the dynamical properties of the magnetic ground state in pure CeFe 2 , as observed in inelastic neutron scattering experiments. 13 The present paper draws on the magnetic-structure determination of Ref.…”

Understanding the element segregation and phase separation in the Ce-substituted Nd-(Fe,Co)-B based alloys

“…The assignment of the six magnetic components is based upon the Wigner-Seitz analysis of the RE 2 Fe l4 B structure 23 , which is even more complicated in the presence of Co 24 . The refined values of hyperfine parameters of the CeFe 2 phase are consistent with those previously reported 11,25 and the remaining paramagnetic component was assigned to the RE-rich phase. From Table 1, the content of the 1:2 phase increases with the increasing Ce content at the expense of the 2:14:1 phase, while that of the RE-rich phase remains almost independent with Ce content.…”

Pressure tuning of competing magnetic interactions in intermetallic CeFe2

“…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] . The proximity of stoichiometric CeFe 2 to an antiferromagnetic instability is also supported by the observation of antiferromagnetic fluctuations within the ferromagnetic phase 9,10,24 .…”

“…Phase diagrams were collected from the literature for CeFe 2 under pressure (Ref. [22,23,25]), Ce(Fe 1−x Co x ) 2 at both ambient (up to 16%, Ref. [17,22,25]) and high pressure (for 5, 7, and 10%, Ref.…”
