Doping-dependent critical Cooper-pair momentum in thin, underdoped cuprate films

John Draskovic, Stanley Steers, Thomas McJunkin +2

We apply a recently-developed low-field technique to inductively measure the critical pair momentum $p_c$ in thin, underdoped films of Y${}_{1-x}$Ca${}_x$Ba${}_2$Cu${}_3$O${}_{7-\delta }$ an…
