The differential susceptibility dM/dB, however, is more rapidly suppressed for B≳16 T than expected from the properties of the low field superconducting state, and saturates at a low value for fields B≳24 T. In addition, torque measurements on a p=0.11 YBCO crystal in pulsed field up to 65 T and temperatures down to 8 K show similar behavior, with no additional features at higher fields. We offer two candidate scenarios to explain these observations: (a) superconductivity survives but is heavily suppressed at high field by competition with charge-density-wave (CDW) order; (b) static superconductivity disappears near 24 T and is followed by a region of fluctuating superconductivity, which causes dM/dB to saturate at high field. The diamagnetic signal observed above 50 T for the p=0.11 crystal at 40 K and below may be caused by changes in the normal state susceptibility rather than bulk or fluctuating superconductivity. There will be orbital (Landau) diamagnetism from electron pockets and possibly a reduction in spin susceptibility caused by the stronger three-dimensional ordered CDW."}],"publisher":"APS","article_processing_charge":"No","extern":"1","language":[{"iso":"eng"}],"issue":"18","publication":"Physical Review B","date_created":"2019-11-19T13:22:06Z","month":"11","date_updated":"2021-01-12T08:11:42Z","volume":92,"_id":"7070","title":"Magnetization of underdoped YBa2Cu3Oy above the irreversibility field","quality_controlled":"1","author":[{"full_name":"Yu, Jing Fei","last_name":"Yu","first_name":"Jing Fei"},{"first_name":"B.
