Phase diagrams and Fermi surface properties ofCePb3

Abstract

We illustrated the phase diagrams and measured the de Haas-van Alphen effect of CePb 3 , which is a heavy fermion compound with an antiferromagnetic transition at 1.1 K. CePb 3 has three phases: antiferromagnetic, spin-flop, and paramagnetic. Three fundamental oscillations denoted by ␣, ␤, and ␥ were observed in the paramagnetic state. Two of them, the ␣ and ␥ branches, are closed and almost spherical. For the ␣ branch, the natural explanation is provided by the results of band calculation. The heaviest cyclotron effective mass was 67m 0 in the ␣ branch of CePb 3 when the magnetic field is applied parallel to ͗100͘. The mass of CePb 3 is in a range of 9.3 to 67m 0 and quite enhanced. Despite the natural explanation in topology, as expected from the quite heavy cyclotron mass, the quasiparticle bands are much flatter and the density of states at the Fermi energy is more enhanced than the calculated one.

A 2D heavy fermion CePb3 kagome material on silicon: emergence of unique spin polarized states for spintronics

“…The (Pb, Ce) system was chosen for two main reasons. First, the CePb 3 bulk material is a heavyfermion type-I antiferromagnet with a Néel transition temperature T N of 1.1 K. 20,21 Magnetic field (15 T) is known to induce superconductivity in the material that stimulates considerable theoretical and practical interest. 22 The intra-atomic spin-orbit coupling (SOC) of the 4f electrons of rare earth elements is large, and thus effective moments of the total angular momentum J > 1/2 encompass both spins and higher multipolar moments.…”

“…The suppression of the superconducting transition temperature by impurities was observed. From the temperature dependence of resistivity for LaPb 3 Kletowski et al [5] estimated the Debye temperature θ as 125 K. Ebihara et al [7] have found the phase diagrams of CePb 3 and they observed three phases: antiferromagnetic, spin op, and paramagnetic. The phase diagram and de Haasvan Alphen (dHvA) eect of PrPb 3 under pressure was also studied by Endo et al [9].…”
