Abstract We have used a low noise Scanning Hall Probe Microscope (SHPM) to study vortex structures in superconducting films. The microscope has high magnetic field (∼2.9×10−8T/√Hz at 77K) and spatial resolution, ∼0.85μm. Magnetic field profiles of single vortices in High Tc YBa2Cu3O7−δ thin films have been successfully measured and the microscopic penetration depth of the superconductor has been extracted as a function of temperature. Flux penetration into the superconductor has been imaged in real time (∼8s/frame).
