Angle Dependence of the Orbital Magnetoresistance in Bismuth
It is known that magnetic fields can affect how electricity is conducted through a solid. Resistivity sometimes increases by orders of magnitude in the presence of a magnetic field, an effect that has been observed in semimetals such as graphite and bismuth. The low-mass electrons in bismuth are very mobile and explain the changes in …

Topology on a new facet of bismuth | PNAS
As a result, the ultraquantum regime is reached in bismuth at a magnetic field as small as 9 T, beyond which a number of correlated electron states have been observed (4–7). Because of bismuth's large spin–orbit coupling, bismuth-based materials have also played a fundamental role in topological physics (8, 9).

Does bismuth have magnetic properties?
By Perrine Juillion / February 22, 2020. Compared to other metals, bismuth is the most diamagnetic; that is, it resists being magnetized and is repelled by a magnetic field, according to Chemicool. It also has low electric conductivity and the greatest electrical resistance when placed in a magnetic field, a trait called the Hall effect.

Bismuth Element Facts
Bismuth is a crystalline, brittle, metal. Lying on the right side of the periodic table, bismuth is the most naturally diamagnetic metal; this means it resists being magnetized and is repelled by a magnetic field. One effect of this can be seen in the video (left). Bismuth also has unusually high electrical resistance for a metal.

Boundary conductance in macroscopic bismuth crystals
Bismuth samples subject to pulsed magnetic fields 8, 36 were small pieces cut from larger crystals and hosted extended scattering centers such as twin boundaries and dislocations. The presence of such disorder led to a shorter electronic mean free path and a significantly lower magnetoresistance compared to the crystals studied here.
