Table 2 Calculated \(\Delta _{VJ}\) values from RTSIRM measurements for each sample, tabulated with dislocation density and coercivity (also in Table 1). \(\Delta_{VJ}\) was calculated by subtracting the minimum magnetization at \(T_{\mathrm{v}}\) from the maximum magnetization approximately 10 K below \(T_{\mathrm{v}}\), as described in Muxworthy et al. (2003)
