A study on stress affecting the microwave surface resistance of YBCO high temperature superconducting thin films

Stress Distributions of Rectangular Thin-Film Superconductor with a Centric Hole

“…Additionally, Patel et al and Kamran et al, respectively, analyzed the matching effect in a superconducting film with holes [11,12], whilst Bentner et al considered the effect of submicron holes on the vortex dynamics of a superconducting microbridge [7]. On the other hand, although lots of achievements on mechanical behaviors of superconducting films have been also obtained [14][15][16][17][18][19][20][21][22][23], the investigations about mechanical properties of thin-film superconductors with holes are very limited. To our best knowledge, up till now, only Feng et al [24] analytically investigated flux-pinning-induced magnetostriction and stress in a transversely isotropic superconducting thin disk with a concentric small hole.…”
