“…In analogy with MR, the non-monotonic field dependence of R H can be understood as the result of two competing effects. The decrease in R H above H c2 is likely due to the field suppression of the spin fluctuations, whereas the increase at higher fields is an effect of having two types of carriers, as inferred from FS studies [20]. Note also that the high field behavior is unchanged with pressure, consistent with the absence of change in the FS up to 12 kbar [21].…”

We report Hall Effect measurements under pressure in the normal state of CeCoIn 5 , from 60 to 355 mK and for fields exceeding the superconducting upper critical field H c2 , with the field oriented parallel to [0 0 1]. At low pressures, the field dependence of the Hall coefficient exhibits a scaling consistent with the one reported in the normal state at higher temperatures, but at odds with the DH=T scaling expected near a field tuned quantum critical point. The breakdown of this scaling at higher pressures, concomitant with the suppression of spin fluctuations, suggests that it is a hallmark of the spin fluctuations. Published by Elsevier B.V.

“…The Fermi surface in the 16th, 17th and 18th band possesses many extremal cross-section in the limited range of angles because of its rugged shape. Due to the similarity of the Fermi-surface structure, the branches labelled by α i , β i , a and b i (i = 1 and 2) are the same as those of CeTIn 5 [46,47] respectively. The dHvA experiments on Pu-115 compounds have not yet been carried out due to several experimental difficulties, but we believe that such experiments will be done in the near future.…”

T h e o p e n -a c c e s s j o u r n a l f o r p h y s i c s Abstract. By using a relativistic linear augmented-plane-wave method with the one-electron potential in the local-density approximation, we investigate energy-band structures and the Fermi surfaces of transuranium compounds NpTGa 5 , PuTGa 5 and AmCoGa 5 with transition metal atoms T. It is found that the energy bands in the vicinity of the Fermi level are mainly due to the large hybridization between 5f and Ga 4p electrons. For PuTGa 5 , we observe several cylindrical sheets of Fermi surfaces with large volume for T = Co, Rh and Ir. The de Haas-vanAlphen (dHvA) frequencies are theoretically estimated for PuCoGa 5 . It is also found that the Fermi surfaces of NpFeGa 5 , NpCoGa 5 and NpNiGa 5 are similar to those of UCoGa 5 , UNiGa 5 and PuCoGa 5 , respectively, except for small details. For AmCoGa 5 , the Fermi surfaces are found to consist of large cylindrical electron sheets and small closed hole sheets, similar to PuCoGa 5 . The similarity is basically understood by the change of electron numbers inside the Fermi surfaces on the basis of a rigid-band picture. We compare our theoretical Fermi surfaces with the experimental results on NpTGa 5 . New Journal of Physics
