Popis:	In Ref. [1], Minkov et al. reported measurements of the magnetic moment that remains after a magnetic field is turned on and then turned off for hydride materials under high pressure in a diamond anvil cell. In Refs. [2,3], Minkov et al. reported magnetization measurements on the same samples as a function of applied magnetic field. Here we argue that the latter indicate that the signal measured in the former does not provide evidence for superconductivity in these samples. Instead, the measured signal likely originates in ferromagnetism of either the sample or the background. Comment: under consideration by Nature Physics as Matters Arising on ref. [1]
