Magnetic force microscopy measurement of the penetration depth in superconductors from Meissner repulsion

Lan Luan, Ophir M. Auslaender, Nadav Shapira +4

We report a method to locally measure the penetration depth $λ$ in a superconductor by detecting the diamagnetic response using magnetic force microscopy (MFM). We extract $λ$ by f…

Local measurement of the superfluid density in the pnictide superconductor Ba(Fe $_{1 - x}$ Co $_{x}$ ) $_{2}$ As $_{2}$ across the superconducting dome

Lan Luan, Thomas M. Lippman, Clifford W. Hicks +6

We measure the penetration depth $λ_{ab} (T)$ in Ba(Fe $_{1 - x}$ Co $_{x}$ ) $_{2}$ As $_{2}$ using local techniques that do not average over the sample. The superfluid density $ρ_s(T)\equiv1/λ…

Mechanics of Individual, Isolated Vortices in a Cuprate Superconductor

Ophir M. Auslaender, Lan Luan, Eric W. J. Straver +7

Superconductors often contain quantized microscopic whirlpools of electrons, called vortices, that can be modeled as one-dimensional elastic objects. Vortices are a diverse playgro…
