de Haas-van Alphen oscillations in the underdoped cuprate YBa${}_2$Cu${}_3$O${}_{6.5}$

C. Jaudet, D. Vignolles, A. Audouard +11

The de Haas-van Alphen effect was observed in the underdoped cuprate YBa${}_2$Cu${}_3$O${}_{6.5}$ via a torque technique in pulsed magnetic fields up to 59 T. Above an irreversibility fi…
