Ten-fold-like magnetic anisotropy in electrical conductivity of Al–Pd–Mn icosahedral quasicrystal

Ten-fold-like magnetic anisotropy is reproducibly observed in electrical conductivity of Al 71Pd 21Mn 8 icosahedral quasicrystal. The voltage V is measured, where the current I is along a five-fold axis of the sample and is perpendicular to the magnetic field H. The voltage difference Δ V= V(+ I)+ V...

Description
Summary:Ten-fold-like magnetic anisotropy is reproducibly observed in electrical conductivity of Al 71Pd 21Mn 8 icosahedral quasicrystal. The voltage V is measured, where the current I is along a five-fold axis of the sample and is perpendicular to the magnetic field H. The voltage difference Δ V= V(+ I)+ V(− I) has angle dependences at H=30∼80 kOe and the temperature T=2∼8 K. Δ V is about 3000 times smaller than V and its 10-fold-like anisotropy comes from small non-linearity of I– V characteristics.
