Figure 3From: Magnetic properties of superparamagnetic nanoparticles loaded into silicon nanotubesZFC/FC measurements of SiNTs (wall thickness 10 nm) filled with iron oxide NPs of 4 and 10 nm in size. One can see that the sample containing 4-nm NPs offers a TB of 10 K, whereas the sample with 10-nm NPs shows two peaks at 45 and 160 K.Back to article page
