Autor: de Visser, A., Graf, M. J., Estrela, P., Amato, A., Baines, C., Andreica, D., Gygax, F. N., Schenck, A.

Publikováno v: Phys. Rev. Lett. 85 (2000) 3005

Transverse-field muon spin relaxation measurements have been carried out on the heavy-fermion superconductor UPt3 doped with small amounts of Pd. We find that the critical Pd concentration for the emergence of the large-moment antiferromagnetic phase

Evidence for a two component magnetic response in UPt3

Autor: Yaouanc, A., de Reotier, P. Dalmas, Gygax, F. N., Schenck, A., Amato, A., Baines, C., Gubbens, P. C. M., Kaiser, C. T., de Visser, A., Keizer, R. J., Huxley, A., Menovsky, A. A.

Publikováno v: Phys. Rev. Lett. 84 (2000) 2702

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 have been found for the field in the basal plane. While the volume fra

Muon localization site in U(Pt,Pd)3

Autor: Schenck, A., Keizer, R. J., de Visser, A., Amato, A., Andreica, D., Gygax, F. N., Pinkpank, M., Estrela, P., Graf, M. J., Menovsky, A. A., Franse, J. J. M.

The angular and temperature (10-250 K) variation of the Knight shift of single-crystalline U(Pt0.95Pd0.05)3 has been measured in transverse field (B=0.6 T) mSR experiments. By analysing the temperature variation of the Knight shift with a modified Cu

Magnetism in heavy-fermion U(Pt,Pd)3 studied by mSR

Autor: Keizer, R. J., de Visser, A., Menovsky, A. A., Franse, J. J. M., Amato, A., Gygax, F. N., Pinkpank, M., Schenck, A.

Publikováno v: J. Phys.: Condens. Matter 11 (1999) 8591-8606

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 the Kubo-Toyabe function. However the temperature variation of the Kubo
