a Experimental (red and orange dots) and theoretical (blue and green lines) normalized reflection (∣S11∣) as a function of the static magnetic field B0 for the BDPA sample (single spin case), highlighting Perfect Absorption. Data are extracted along the horizontal lines shown in Fig. 2a (at fixed frequency, \({\omega }_{1}^{0}\) and \({\omega }_{2}^{0}\)). b Experimental (red dots) and theoretical (blue lines) normalized reflection, ∣S11∣, obtained for the VOTPP crystal (position #A) under PA and based on the horizontal lines illustrated in Fig. 4b (see \({\omega }_{3}^{0}\) and \({\omega }_{4}^{0}\)).
