Standardizing critical current density measurements in lithium garnets [PDF]

Communications Chemistry, 2023
The formation of Li dendrites at the Li/electrolyte interface at practically relevant current densities (> 1 mA cm−2) is a critical issue hindering the deployment of non-flammable and non-toxic Li7La3Zr2O12 (LLZO) electrolyte in solid-state batteries. In

Critical Current Density and Resistivity of MgB2 Films [PDF]

Applied Physics Letters, 2003
The high resistivity of many bulk and film samples of MgB2 is most readily explained by the suggestion that only a fraction of the cross-sectional area of the samples is effectively carrying current.

Determination of critical current density from arbitrary flux relaxation process

AIP Advances, 2012
The current-carrying ability of a type-II superconductor is generally represented by its critical current density. This can be determined by measuring a flux relaxation process starting with a testing current density that is greater than or equal to the ...

Estimation of Cooper pair density and its relation to the critical current density in Y(Ca)BCO high-Tc cuprate superconductors

Results in Physics, 2020
Hole concentration (p) in the CuO2 plane largely controls all the electronic properties in the normal and superconducting states of high-Tc cuprates. The critical current density, Jc, is no exception.
