Angular dependence of domain wall resistivity in artificial magnetic domain structures.
We exploit the ability to precisely control the magnetic domain structure of perpendicularly magnetized Pt/Co/Pt trilayers to fabricate artificial domain wall arrays and study their transport properties. The scaling behavior of this model system confirms the intrinsic domain wall origin of the magnetoresistance, and systematic studies using domains patterned at various angles to the current flo...
متن کاملDomain wall resistivity in SrRuO3.
SrRuO3 is an itinerant ferromagnet with T(c) approximately 150 K. When SrRuO3 is cooled through T(c) in zero applied magnetic field, a stripe domain structure appears whose orientation is uniquely determined by the large uniaxial magnetocrystalline anisotropy. We find that the ferromagnetic domain walls clearly enhance the resistivity of SrRuO3 and that the enhancement has different temperature...
متن کاملResistivity due to Domain Wall Scattering
Domain walls in ferromagnetic metals are known to be a source of resistance since the early experiments on iron whiskers. Recently it has been possible to identify this contribution from data on cobalt and nickel films which display stripe domains in which the current is driven normal to the domain walls. With the same Hamiltonian as used to explain giant magnetoresistance in structures with co...
متن کاملDomain wall resistivity in epitaxial thin film
This article reviews our recent experimental studies of domain wall (DW) resistivity in epitaxial transition metal ferromagnetic thin film microstructures with stripe domains. The results are presented and analysed in the context of models of DW scattering and conventional magnetoresistance (MR) effects in ferromagnetic metals. Microstructures of progressively higher magnetic anisotropy and thu...
متن کاملAngular Dependence of Wall Correction for Cylindrical Cavity Chamber
Abstract The cylindrical graphite cavity chambers are used for primary standard of air kerma rate of Co-60 and Cs-137. We measured wall attenuation correction factor (Kat) at several irradiation angles using extrapolation technique because of angular dependence. From these results, it can be seen that it is insufficient technique for evaluation of Kat. The Monte Carlo simulations were also done...
