2D FERROMAGNETIC

How can one ensure the measured magnetic signal is not coming from impurities in vdW crystals? More specifically magnetic Fe, Co, Ni impurity atoms or their oxides commonly appear in vdW crystals in no care is taken. Our magnetic crystals are grown slowly using top-notch flux zone growth technique for  highest quality crystallization. This method does not use any transporting agent and does not contaminate the crystal these impurities. Special care is given to using highest purity precursors that are free of magnetic transition metal series and their oxides . This allows us to synthesize 99.9995% or higher purity magnetic vdW crystals and access their magnetic behavior without any concern over magnetic impurity contribution.
