On the magnetic and electronic properties of NpPdSn
K. Shrestha, D. Antonio, J-C. Griveau +5
We have studied NpPdSn by means of the heat capacity, electrical resistivity, Seebeck and Hall effect, Np Mössbauer spectroscopy, and neutron diffraction measurements in th…
Probing magnetism in the vortex phase of PuCoGa by X-ray magnetic circular dichroism
N. Magnani, R. Eloirdi, F. Wilhelm +6
We have measured X-ray magnetic circular dichroism (XMCD) spectra at the Pu absorption edges from a newly-prepared high-quality single crystal of the heavy fermion superc…
Thermoelectric power as a probe of density of states in correlated actinide materials: the case of PuCoGa superconductor
K. Gofryk, J-C. Griveau, P. S. Riseborough +1
We present measurements of the thermoelectric power of the plutonium-based unconventional superconductor PuCoGa. The data is interpreted within a phenomenological model for t…
Unusual Behaviour of (Np,Pu)B2C
Tomasz Klimczuk, Pascal Boulet, Jean-Christophe Griveau +5
Two transuranium metal boron carbides, NpB2C and PuB2C have been synthesized by argon arc melting. The crystal structures of the {Np,Pu}B2C compounds were determined from single cr…
Magnetic, electrical and thermodynamic properties of NpIr: ambient and high pressure measurements, and electronic structure calculations
H. C. Walker, K. A. McEwen, J. -C. Griveau +5
We present bulk property measurements of NpIr, a newly synthesized member of the Np-Ir binary phase diagram, which is isostructural to the non-centrosymmetric pressure-induced ferr…
Magnetic polarization of the americium ground state in AmFe
N. Magnani, R. Caciuffo, F. Wilhelm +7
Trivalent americium has a non-magnetic ( = 0) ground state arising from the cancelation of the orbital and spin moments. However, magnetism can be induced by a large molecular f…
