Hall effect through magnetic phase transitions in Nd2Fe14B

We have observed large variations of the Hall effect in the vicinity of magnetic phase transition points. Sharp peaks near the spin-reorientation and Curie temperatures are observed in Hall effect data from Nd2Fe14B single crystals. The effect is very sensitive to the applied magnetic field directio...

Sumario:We have observed large variations of the Hall effect in the vicinity of magnetic phase transition points. Sharp peaks near the spin-reorientation and Curie temperatures are observed in Hall effect data from Nd2Fe14B single crystals. The effect is very sensitive to the applied magnetic field direction near the spin-reorientation temperature. Away from these critical regions the Hall resistivity is proportional to the square of the total resistivity. Different scattering mechanisms dominate in different regions.
