摘要：
Locally applied magnetic fields can be used to create vortex-antivortex pairs in superconducting films and thin crystals. These pairs typically annihilate on some timescale which depends on temperature. We use a 21 mum diameter field coil integrated onto a scanning superconducting quantum interference device to create and observe vortex-antivortex pairs. We present measurements of the distribution of annihilation times as a function of temperature, which should allow us to determine the pinning forces for vortices in these highly underdoped samples of YBa2Cu3O6.354.
