Electrical resistivity of holmium hydride films

Anisotropic electrical resistivity during annealing of oriented columnar titanium films

We report on the evolution of anisotropic electrical resistivity versus temperature of titanium thin films. An oriented titanium film (1 μm thick) is sputter deposited by GLancing Angle Deposition (GLAD) using an incident angle α = 80° of the particle flux. Two parallel Ti electrodes cover this GLAD film. We measure the components of the conductivity tensor by the van der Pauw method during an ...

Logarithmic Divergence of the Electrical Resistivity in the Metal Hydride YH32d

As reported earlier, the metal hydride YHx reveals spectacular switchable optical properties. In this Letter we report on another remarkable property of the hydrogen deficient YH32d trihydride phase. A logarithmic temperature dependence of the electrical resistivity is observed within a large temperature range s20 # T # 200 Kd for hydrogen deficiencies 0.01 , d , 0.15. This dependence may be re...

Anomaly of the electrical resistivity of polyvalent metal films with additions of Mn (and Fe)

2014 Polyvalent metal films with dissolved magnetic additions are produced by quench condensation onto a substrate held at 10 K. The films are subsequently annealed at higher temperature Ta. The electrical resistance is measured below Ta. The alloys In + 1 at % Mn, Pb + 0.8 at % Mn and Pb + 2.4 at % Fe do not show a resistance minimum. The resistance of Sn + 0.2 at % Mn and of A1 + 1 at % and 2...

Role of volume versus defects in the electrical resistivity of lattice-distorted V(001) ultrathin films

4 nm thick V layers grown by triode sputtering on MgO 001 single crystals and capped with MgO exhibit a perfect epitaxy accompanied by a tetragonal distortion and an unexpected volume compression that increases with the V deposition temperature. The electrical resistivity follows a deposition temperature dependence with these structural modifications, decreasing by an order of magnitude across ...
