We consider “swept regions”Ω and “swept hypersurfaces”B in R n+1 (and especially R) which are a disjoint union of subspaces Ωt = Ω∩Πt or Bt = B∩Πt obtained from a varying family of affine subspaces {Πt : t ∈ Γ}. We concentrate on the case where Ω and B are obtained from a skeletal structure (M, U). This generalizes the Blum medial axis M of a region Ω, which consists of the centers of interior ...

We consider a 2D electron system in a strong magnetic field, where the local Hall resistivity ρxy(r) is a function of position and ρxx(r) is small compared to ρxy. Particularly if the correlations fall off slowly with distance, or if fluctuations exist on several length scales, one finds that the macroscopic longitudinal resistivity Rxx is only weakly dependent on ρxx and is approximately propo...

2014 Peaks in magnetoresistance at the same magnetic field as the steps in the Hall voltage are observed in (TMTSF)2ClO4. These measurements were performed between 0.1 and 1.2 K, in magnetic fields up to 8.3 T, on a sample having a resistivity ratio R(T = 300 K, H = 0)/R(T ~ 0, H ~ 0) > 1 600. These results are discussed within a model associating the quantum Hall effect with phase transit...

A systematic study of the resistivity (p), the Hall coefficients (R~), and the magnetic susceptibilities (y) of the Zr-based paramagnetic amorphous alloys suggests a self-consistent explanation for the frequently observed positive values of RH that is based on the side-jump effect. Measurements for g, RH, and p of (Zr064CuQ 36)& Al and g for (Zr05oNi050)& „Al alloys are presented. The odd behav...

Temperature dependences of the extraordinary Hall coeficient R, and resistivity p, yield a m p 2 (arising from the side-jump mechanism) for the majority of investigated FeCoNi-based alloys. The deviation from p2 variation in Co-rich alloys is probably due to the temperature dependence of the magnetic anisotropy in these alloys. One of the characteristic features of amorphous ferromagnetic alloy...
