We examine the behavior of natural basaltic and trachytic samples during paleointensity experiments on both the original and laboratory-acquired thermal remanences and characterize the samples using proxies for domain state including curvature (k) and the bulk domain stability parameters of Paterson (2011, https://doi.org/10.1029/2011JB008369) and Paterson et al. (2017, https://doi.org/10.1073/pnas.1714047114), respectively. A curvature value of 0.164 (suggested by Paterson, 2011, https://doi.org/10.1029/2011JB008369) as a critical threshold that separates single-domain-like remanences from multidomain-like remanances on the original paleointensity data was used to separate samples into “straight” (single-domain-like) and “curved” (multidomain-like) groups. Specimens from the two sample sets were given a “fresh” thermal remanent magnetization in a 70
