a, b Typical hysteresis loops before (blue) and after (red) paramagnetic correction, respectively. c Day plot. d, e Typical FORC diagrams. fh Typical thermomagnetic curves heated in air. Red line represents the heating procedure. Blue line represents the cooling procedure. i Typical IRM acquisition curve. j Result of IRM decomposition of (i). Black dots represent first-order differentiation of the originally measured IRM acquisition curve. Red solid lines represent the decomposed coercivity components. Green solid line represents an accumulation of all components indicated by red solid lines
