Extended Data Fig. 2: Temperature dependence of the magnetic susceptibility for LuH2±xNy at ambient pressure.

From: Absence of near-ambient superconductivity in LuH2±xNy

Extended Data Fig. 2

a, Temperature dependence of magnetic moment for LuH2±xNy (upper part) along with background signal (lower part) measured in an applied field of 10 Oe using both the ZFC and FC modes. b, The corresponding magnetic susceptibility 4πχ with the background subtracted, for a superconductor we should expect 4πχ = −1. In calculating the magnetic susceptibility, we have used a density of 9.22 g/cm2 quoted for compound LuH2. The measurements were carried out by using the SQUID-VSM with a vibrating amplitude of 5 mm and frequency of 13.01 Hz.
