Extended Data Fig. 5: Magnetization relaxation time constants from flux noise spectra.
From: Magnetic monopole noise
Time constant obtained from fits to the measured SΦ(ω, T) data shown in Fig. 3. The time constant τ(T) derived from the flux noise behaves in a super-Arrhenius fashion, τ(T) = τ0exp[DT0/(T – T0)], consistent with previous measurements of a.c. susceptibility time constants τM(T) (ref. 35), which also exhibited super-Arrhenius behaviour with τ0 ≈ 1.4 × 10−4 s, D ≈ 14, T0 ≈ 0.26 K.
