Evidence for a two component magnetic response in UPt3
A. Yaouanc, P. Dalmas de Reotier, F. N. Gygax +9
The magnetic response of the heavy fermion superconductor UPt_3 has been investigated on a microscopic scale by muon Knight shift studies. Two distinct and isotropic Knight shifts…
Search for a quantum phase transition in U(Pt_(1-x)Pd_x)_3
M. J. Graf, R. J. Keizer, A. de Visser +1
Pd in U(Pt_{1-x}Pd_x)_3 suppresses the superconducting T_c to 0 K at critical concentration x_c of 0.007 and induces a conventional AFM state for x > x_c. The resistivity below 1 K…
Magnetism in heavy-fermion U(Pt,Pd)3 studied by mSR
R. J. Keizer, A. de Visser, A. A. Menovsky +5
We report mSR experiments carried out on a series of heavy-electron pseudobinary compounds U(Pt1-xPdx)3 (x<=0.05). For x<=0.005 the zero-field muon depolarisation is described by t…
Superconductivity in heavy-fermion U(Pt,Pd)3 and its interplay with magnetism
R. J. Keizer, A. de Visser, M. J. Graf +2
The effect of Pd doping on the superconducting phase diagram of the unconventional superconductor UPt3 has been measured by (magneto)resistance, specific heat, thermal expansion an…
Neutron-diffraction study of the evolution of antiferromagnetic order in UPt3 doped with Pd
R. J. Keizer, A. de Visser, A. A. Menovsky +3
Neutron-diffraction experiments have been carried out on U(Pt1-xPdx)3 single crystals (x<= 0.05). The small-moment antiferromagnetic order (SMAF) reported for pure UPt3 is robust u…
Suppression of Superconductivity in Single Crystals of UPt_3 by Pd Substitution
M. J. Graf, R. J. Keizer, A. de Visser +2
The suppression of superconductivity by substitution effects has been measured in high quality single crystals of U(Pt_{1-x} Pd_x)_3 with 0 <= x <= 0.002. While the superconducting…
