Absorption lines derivatives, 𝑑𝜒^/𝑑𝐻_dc, resulting from the computer simulations in the case when magnetic anisotropy axes orientations represent a chain-like structure of 𝑁=40 magnetic nanoparticles oriented into 𝑧-direction, chain-like structure of 𝑁=40 nanoparticles oriented into 𝑥-direction, or they represent a random cluster consisting of 𝑁=80 and 𝑁=200, respectively. The parameters of the computer simulation have only a qualitative meaning and they have been taken the same as in [5].
