Model for the magnetoresistance and Hall coefficient of inhomogeneous graphene [PDF]

open access: yes, 2008
We show that when bulk graphene breaks into n-type and p-type puddles, the in-plane resistivity becomes strongly field dependent in the presence of a perpendicular magnetic field, even if homoge- neous graphene has a field-independent resistivity.

The role of geophysics in enhancing mine planning decision-making in small-scale mining [PDF]

open access: yesRoyal Society Open Science, 2020
Small-scale mining usually operates under high geological uncertainty conditions. This turns mine planning into a complex and sometimes inaccurate task, resulting in low productivity and substantial variability in the quantity and quality of the mineral ...

The structural and dielectric properties of lanthanum substituted strontium based spinel ferrites nano-materials for high frequency device applications

open access: yesJournal of Taibah University for Science, 2023
Lanthanum substitution on spinel Nano particles has a significant repercussion on the several features of materials. Sol–gel (auto-ignition) allowed for the substitution of the rare earth lanthanum ion (La3+) for spinel ferrite with composition SrLaxFe2 ...

Deviations from Matthiessen rule and resistivity saturation effects in Gd and Fe [PDF]

open access: yes, 2013
According to earlier first-principles calculations, the spin-disorder contribution to the resistivity of rare-earth metals in the paramagnetic state is strongly underestimated if Matthiessen's rule is assumed to hold.
