Phys. Rev. Lett. 59, 2592–2595 (1987)Observation of Hexagonally Correlated Flux Quanta In YBa2Cu3O7Received 26 August 1987; published in the issue dated 30 November 1987 The high-resolution Bitter pattern technique has been used to reveal the magnetic structure of single-crystal samples of high-Tc superconductor YBa2Cu3O7 at 4.2 K. Typical patterns consist of hexagonally correlated, singly quantized vortices of flux hc/2e. That is, the structures are comparable to those that would be observed in conventional type-II superconductors under similar conditions. © 1987 The American Physical Society URL:
