High-pressure measurements of the resistivity of americium metal are reported to 27 GPa and down to temperatures of 0.4 K. The unusual dependence of the superconducting temperature (T(c)) on pressure is deduced. The critical field [H(c)(0) extrapolated to T=0] increases dramatically from 0.05 to approximately 1 T as the pressure is increased, suggesting that the type of superconductivity is changing as pressure increases. At pressures of approximately 16 GPa the 5f electrons of Am are changing from localized to itinerant, and the crystal structure also transforms to a complex one. The role of a Mott-type transition in the development of the peak in T(c) above 16 GPa is postulated. 相似文献

The present study of Np2Ir2In completes the 237Np Mössbauer spectroscopy investigations of Np2T2X (T = Co, Rh, Ir, Ni, Pd, Pt; X = In, Sn) compounds. Np2Ir2In is found to order at T
ord30 K and the complex Mössbauer spectra suggest the occurrence of a noncollinear modulated magnetic structure with an average magnetic moment on the neptunium Np0.76 B. The magnetic properties of Np2Ir2In are consistent with the general trends observed in the An2T2X (An =U, Np) isostructural family. 相似文献
