Table 2 Four distinct field scales identified in this study

From: Magnetic memory and distinct spin populations in ferromagnetic Co3Sn2S2

Field scale

Amplitude (T)

Definition

\({B}_{0}^{\star }\) (T)

0.4

Spin-flip field in absence of memory (coercivity of main spin population)

\({B}_{\rm{max}}^{\star }\) (T)

3

Sweeping field above which no memory persists (maximum coercivity of secondary spin population)

\({B}_{0}^{bt}\) (T)

0.085

Hysteresis becomes bow-tie when the spin-flip field falls below this threshold

\({B}_{\rm{max}}^{bt}\) (T)

0.35

Hysteresis becomes bow-tie when the magnetic field is swept below this threshold

  1. The amplitudes are given for sample 1 at T = 10 K. \({B}_{0}^{\star }\) and \({B}_{0}^{bt}\) refer to spin-flip fields, at which the magnetic field shows an abrupt jump. \({B}_{\rm{max}}^{bt}\) and \({B}_{\rm{max}}^{\star }\) refer to maximum sweeping field tuning the spin-flip field, B0. \({B}_{0}^{bt}\) and \({B}_{\rm{max}}^{bt}\) depend on the demagnetizing factor and show little dependence on temperature. \({B}_{\rm{max}}^{\star }\) and \({B}_{0}^{\star }\) both decrease with warming.
