Direct observation of quadrupolar excitons in the heavy-fermion superconductor PrOs4Sb12.
We report inelastic neutron scattering experiments performed to investigate the low energy magnetic excitations on single crystals of the heavy-fermion superconductor PrOs(4)Sb(12). The observed excitation clearly softens at a wave vector Q=(1,0,0), which is the same as the modulation vector of the field-induced antiferro-quadrupolar ordering, and its intensity at Q=(1,0,0) is smaller than that...
متن کاملSimple model for coupled magnetic and quadrupolar instabilities in uranium heavy-fermion materials.
We present a mean-field calculation of the phase diagram of a simple model of localized moments, in the hexagonal uranium heavy-fermion compounds. The model considers a non-Kramers quadrupolar doublet ground state magnetically coupled with a singlet excited-state, favoring in-plane van-Vleck magnetism, as has been conjectured for UPt3. The Hamiltonian which defines the model is Heisenberg like ...
متن کاملHall effect in the heavy-fermion compound CePtSi.
We present Hall effect measurements on the heavy fermion compound CePtSi. Above the nee1 temperature the behavior of the Hall effect is that generally observed in heavy fermion compounds and ascribed to skew scattering. Below TN the Hall effect is enhanced and its stronly non-linear field dependence evidences the existence of a field-induced phase transtion. We discus the origin of the enhancem...

نتایج این مطالعه نشان می دهد که مقدار کلسیم (یونیزه و تام)، منیزیم و فسفر به طور معنی داری تغییر پیدا کرد به جزء مقدار کلسیم تام و منیزیم در روش داخل عضلانی که تغییر معنی داری نداشته است. بر اساس نتایج این مطالعه می توان نتیجه گیری کرد که اکسی تتراساکلین بر روی مقادیر سرمی کلسیم و منیزیم تأثیر می گذارد باید مقدار این کاتیون ها در بیماران، در هنگامی که اکسی تتراسایکلین استفاده می شود مورد توجه ق...
15 صفحه اولEffect of pressure on magnetic structure in heavy fermion CeRhIn5
The effect of hydrostatic pressure on the incommensurate antiferromagnetic structure of CeRhIn5 is investigated with neutron diffraction using a He pressure cell. At 3.8 kbar, the staggered magnetic moment is 0.37(4) μB per Ce at 1.6 K, which is the same as the ambient-pressure value. The Néel temperature TN = 3.8(1) K is also the same as the ambient-pressure one, although the curve of order pa...
