Hysteretic superconducting resistive transition in Ba0.07K0.93Fe2As2

Taichi Terashima, Kunihiro Kihou, Megumi Tomita +7

We have observed hysteresis in superconducting resistive transition curves of Ba${}_{0.07}$K${}_{0.93}$Fe${}_2$As${}_2$ ($T_c\sim$8 K) below about 1 K for in-plane fields. The hysteresis i…
