The main physical, chemical and magnetic properties of the samples are shown in Table 2.The XRD results (Fig. 1 and Table 2) indicate that all samples are dominated by hematite, goethite being present in small proportion only in J12, L3, and S8.The ratio between the intensities of (1 1 0) and (1 0 4) reflections (which pertain to a …

2. The magnetic haematite beads commonly sold as being good for you in some ill defined way are actually a mixture of haematite and magnetite. The magnetic field is generated by the magnetite. At room temperature haematite is weakly ferromagnetic but not enough to be easily noticeable. It is only paramagnetic above 948K.

To their surprise, they found hidden patterns of magnetic charges within hematite, including monopoles, dipoles, and quadrupoles. "Monopoles had been predicted theoretically, but this is the first time we've actually seen a two-dimensional monopole in a naturally occurring magnet," said co-author Professor Paolo Radaelli, from the ...
