The magnetoresistance of aluminium residual resistivity of the sample was x ratio (RRR) of 25 i Om, giving a residual resistance Magnet The magnet used for the high field measurements was a BOC superconducting magnet with two coils arranged as a Helmholtz pair.

This produced a horizontal field ofCited by: 1. We report oscillatory magnetoresistance in various superconducting films, with a magnetic-field period ΔB∼ T that is essentially independent of sample dimensions, temperature, transport.

It was then proposed that half-quantum vortices may be stabilized in the ground state of perforated superconducting films, which can be observed by magnetoresistance measurement For a.

GIXRD measurements indicate formation of nano-crystalline molybdenum nitride thin films. The transition temperature of MoN thin film is K. The transition width is less than K. The upper critical field Bc2(0), calculated using GLAG theory is : R.

The growth of very thin aluminum oxide and aluminum nitride tunnel barriers on top of an about 7 nm aluminum layer is deduced by measurements of the reflectivity change of a laser beam due to the.

Polycrystalline‐aluminum‐tape samples of ×6 mm 2 cross section have been used to measure the zero‐field resistivity and the transverse magnetoresistance up to T.

The main purpose of our investigation was to study the temperature and purity dependence of the magnetoresistance. Measurements were taken continuously in the temperature range –32 K for six samples differing.

The resistivity measurements were performed in either a superconducting magnet with a maximum field of 15 T, using a 3 He cryostat, or a resistive magnet of 33 T with a 4 He cryostat with base temperature K.

We mounted the samples on a rotatable. The measurement setup was the same that was used in Negative magnetoresistance is observed in the thinnest wire Touboltsev V and Arutyunov K Y Quantum fluctuations in ultranarrow superconducting aluminum nanowires Phys.

The unusual superconducting properties of granular aluminum oxide have been recently investigated for application in quantum circuits.

However, the intrinsic irregular structure of this material requires a good understanding of the transport mechanisms and, in particular, the effect of disorder, especially when patterned at the nanoscale level.

In view of these aspects, electric transport and. Aluminum Magnet Construction The construction of the aluminum coils is shown in figure V, Each turn of the magnet is a composite structure providing the current path, structural strength, coolant passages, and insulation. The high-purity aluminum conductor is 5 centi.

In addition, an experiment is in preparation which will measure the magnetoresistance of copper and aluminum in fields up to 12 tesla after MeV neutron irradiation. The same experiment will test the effects of repeated irradiation and room temperature annealing on NbTi critical current.

Jukka Pekola, in Encyclopedia of Physical Science and Technology (Third Edition), IV.A General. An NIS tunnel junction can be readily made between a number of material combinations.

The simplest example with nearly ideal performance is provided by aluminum-aluminum oxide-copper, where aluminum is the superconductor at sub-kelvin temperatures and copper is one of the possible normal.

The origin of the sample dependence of R H in T' cuprates was clarified from the systematic studies varying the reduction condition to remove O ap impurities.

It turned out that R H shifts toward a more positive value with reduction. Figure shows the data by Brinkmann et al.
