Journal ArticleDOI
Magnetic-field-induced charge-stripe order in the high-temperature superconductor YBa2Cu3Oy.

TL;DR: Nuclear magnetic resonance measurements are reported showing that high magnetic fields actually induce charge order, without spin order, in the CuO2 planes of YBa2Cu3Oy, and it is argued that it is most probably the same 4a-periodic modulation as in stripe-ordered copper oxides.
Journal ArticleDOI
Incipient charge order observed by NMR in the normal state of YBa2Cu3Oy
Tao Wu,Hadrien Mayaffre,Steffen Krämer,Mladen Horvatić,Claude Berthier,Walter Hardy,Ruixing Liang,D. A. Bonn,Marc-Henri Julien +8 more
TL;DR: It is shown that the short-ranged charge order recently reported in the normal state of YBa2Cu3Oy corresponds to a truly static modulation of the charge density, and that this modulation impacts on most electronic properties, and it appears jointly with intra-unit-cell nematic, but not magnetic, order.
Journal ArticleDOI
Emergence of charge order from the vortex state of a high-temperature superconductor.
Tao Wu,Hadrien Mayaffre,Steffen Krämer,Mladen Horvatić,Claude Berthier,Philip L. Kuhns,A. P. Reyes,Ruixing Liang,Ruixing Liang,Walter Hardy,Walter Hardy,D. A. Bonn,D. A. Bonn,Marc-Henri Julien +13 more
TL;DR: It is shown using nuclear magnetic resonance that charge order in YBa2Cu3Oy has maximum strength inside the superconducting dome, similar to compounds of the La2-x(Sr,Ba)xCuO4 family, and that the overlap of halos of incipient charge order around vortex cores can explain the threshold magnetic field at which long-range charge order emerges.
Journal ArticleDOI
Spin susceptibility of charge-ordered YBa2Cu3Oy across the upper critical field

TL;DR: It is found that χspin increases (most likely linearly) with magnetic field H and saturates above field values ranging from 20 T to 40 T, consistent with the lowest Hc2 values claimed previously and with the interpretation that the charge density wave (CDW) reduces Hc1 in underdoped YBa2Cu3Oy.
