Discovery of slow magnetic fluctuations and critical slowing down in the pseudogap phase of YBa$_2$Cu$_3$O$_y$

Autor: Zhang, Jian, Ding, Z. F., Tan, C., Huang, K., Bernal, O. O., Ho, P. -C., Morris, G. D., Hillier, A. D., Biswas, P. K., Cottrell, S. P., Xiang, H., Yao, X., MacLaughlin, D. E., Shu, Lei

Evidence for intra-unit-cell (IUC) magnetic order in the pseudogap region of high-$T_c$ cuprates below a temperature $T^\ast$ is found in several studies, but NMR and $\mu$SR experiments do not observe the expected static local magnetic fields. It ha

The microscopic study of a single hydrogen-like impurity in semi-insulating GaAs

Autor: Eshchenko, D. G., Storchak, V. G., Cottrell, S. P., Morenzoni, E.

The charge dynamics of hydrogen-like centers formed by the implantation of energetic (4 MeV) muons in semi-insulating GaAs have been studied by muon spin resonance in electric fields. The results point to the significant role of deep hole traps in th

Evidence for weak itinerant long-range magnetic correlations in UGe2

Autor: Yaouanc, A., de Reotier, P. Dalmas, Gubbens, P. C. M., Kaiser, C. T., Menovsky, A. A., Mihalik, M., Cottrell, S. P.

Publikováno v: Phys. Rev. Lett. 89 (2002) 147001

Positive muon spin relaxation measurements performed on the ferromagnet UGe2 reveal, in addition to the well known localized 5f-electron density responsible for the bulk magnetic properties, the existence of itinerant quasi-static magnetic correlatio
