These compounds largely crystallize in olivine structure type. The proportional It was found that chromium is fully occupied at the Mn-site while iron distributes itself to both Mn- (mostly) and Sn-site (partly) generating different degree of disorder upon substitution. Electric currents and the magnetic moments of elementary particles give rise to a magnetic field, which acts on other currents and magnetic moments. However, in Fe-doped compounds, a striking phenomenon was observed, as the first transition temperature (around 53 K for pure compound) completely disappeared while the second transition temperature (152 K in the pure compound) increased with higher amount of Fe substitution (around 174 K for 9% of Fe). WebThis wire is moving in a magnetic field, so the $\FLPv\times\FLPB$ forces will cause the ends of the wire to be charged (they will charge up until the $\FLPE$-field from the charges just balances the $\FLPv\times\FLPB$ force).
