We have carried out μ SR spectroscopy on polycrystalline UNiGe between 2 K and 100 K. The existence of two magnetic transitions at T N = 51 K and T 1 = 41.5 K is confirmed. The μ SR spectra clearly reveal that the magnetic state between 51 K and 41

Positive-muon spin rotation (μ+SR) spectroscopy and magnetic moment measurements were used to probe fluxon (or vortex) formation in the superconducting mixed state of a high-purity YBa2Cu3O7 crystal. Random potentials caused by crystal-lattice defec

Muon spin relaxation (µSR) in the singlet ground-state compounds PrP and PrP0.9 reveals the unusual situation of a Lorentzian local field distribution with fast-fluctuation-limit strong-collision dynamics, a case that does not show motional narrowin

Muon spin rotation measurements are reported for GdSr2Cu2RuO8, a material with an onset temperature for superconductivity of about 45 K (which is virtually the same for its superconducting sister compounds Sr2YRu1− u Cu u O6 and Gd2− z Ce z Sr2Cu

The temperature and field dependence of the penetration depth was determined from muon spin rotation (μ+ SR ) measurements on a single crystal of YBa 2 Cu 3 O 7 having a superconducting transition at Tc ≈ 91.3 K . Data were acquired at applied mag

Muon spin rotation and electron spin resonance data on sintered samples of superconducting Sr 2 Y(Ru 1− u Cu u )O 6 and non-superconducting Ba 2 Gd(Ru 1− u Cu u )O 6 are reported, both for u =0.1. In the case of Sr 2 Y(Ru 1− u Cu u )O 6 , the S

For some time now, there has been considerable experimental and theoretical effort to understand the role of the normal-state “pseudogap” phase in underdoped high-temperature cuprate superconductors. Recent debate has centered on the question of

We report muon spin rotation studies of the magnetic field distribution n ( B μ ) of the low-temperature ( T =5 K) vortex state of the high- T c superconductor Bi 2 Sr 2 CaCu 2 O 8+δ (Bi-2212) in an underdoped state ( T c =77 K). In agreement with

The magnetic and superconducting characteristics of sintered Sr2YRu1−uCuuO6 (for u=0.05, 0.10, 0.15) were probed using transverse- and zero-field muon-spin rotation (μ+SR). Since positive muons are attracted to oxygen ions in the high-TC oxides, S

μSR studies in zero, longitudinal and transverse fields were carried out in the temperature range between 2 and 150 K on a polycrystalline powder sample. The data confirm the presence of two magnetic states, but each contains differently correlated
