Figure 4. Results of magnetic susceptibility analysis.

Figure 4A shows the curve fits of the Brillouin function with diamagnetic contribution (Equation 1) to the magnetization versus magnetic field data (for whole eggs at a temperature of 5 K). It can be seen that ideal paramagnetic behavior is approximated with good precision. (R²>0.99) for both, Schistosoma mansoni and Schistosoma japonicum eggs. Figure 4B shows the curve fits of Curie's law to the magnetization versus inverse temperature data. Again, ideal paramagnetic behavior can be observed. For S. mansoni the total magnetic moments were approximated to 4.84×μ_B using the Brillouin function and 4.76×μ_B using Curie's law. For S. japonicum the total magnetic moments were approximated to 4.12×μ_B using the Brillouin function and 3.71×μ_B using Curie's law.
