Magnetization loops obtained at 2 and 300 K. M(H) loops after subtraction of the diamagnetic component from the substrate; insert: sample PL-2. (a) at 2 K and (b) at 300 K. (c) Derivative of experimental and theoretical M(H) loops for sample PP, evidencing the coexistence of two magnetic components. (d) Ferromagnetic component isolated from M(H) hysteresis loops from measurements at 2 K.
