Cooper The physics of underdoped cuprates has been an unresolved longstanding problem. New measurements at ultrahigh magnetic fields on underdoped YBCO are used to show that superconducting diamagnetism survives at fields far above the irreversibility line at low temperatures. Two scenarios can account for these observations - superconductivity competes with charge order and is considerably diminished or a fluctuating superconductivity survives above a certain magnetic field.
