Magnetic properties of hematite (α-Fe2O3) nanoparticles prepared by hydrothermal synthesis method

- Hematite nanoparticles are synthesized by using the hydrothermal synthesis method.
- The SQUID measurements show blocking temperature TB = 52 K and superparamagnetism.
- A TEM measurements show spherical particles and narrow size distribution.
- The sample did not exhibit the Morin transition.
- The magnetic moment μp = 657 μB and diameter d = 8 nm were determined.
