The Superconducting Transition and Mixed State of YBa${}_2$Cu${}_3$O${}_{6.95}$: An Undergraduate Experiment

Zhongda Huang, Yihang Tong, Jake S. Bobowski

We describe a simple AC susceptometer built in-house that can be used to make high-resolution measurements of the magnetic susceptibility of high-temperature superconductors in an…
