On the estimating the superconducting volume fraction from the internal magnetic susceptibility
Aleksandr V. Korolev, Evgeny F. Talantsev
Zhang et al. reported zero-field cooled (ZFC) and field cooled (FC) data measured in a highly compressed single crystal. These measurements provide unambiguous…

Threefold error in the reported zero-field cooled magnetic moment of single crystal
Aleksandr V. Korolev, Evgeny F. Talantsev
For a relatively long time, the observation of the DC diamagnetic state in highly compressed nickelate superconductors [1],[2] has been a challenging experimental problem. And rece…

Nearly twofold overestimation of the superconducting volume fraction in pressurized Ruddlesden-Popper nickelates
Aleksandr V. Korolev, Evgeny F. Talantsev
The detection of the DC diamagnetic state in pressurized Ruddlesden-Popper nickelates remained an unsolved experimental problem until recent experiments in which Zhu et al. mea…
