Bismuth Bound

Bismuth's strong diamagnetism arises from its unique rhombohedral crystalline structure (a distorted cubic system) and its electronic band structure.

In this structure, bismuth atoms are arranged in a layered, anisotropic fashion, leading to highly directional electronic properties.

The material exhibits low carrier density and high effective electron mass, reducing its ability to sustain internal currents when exposed to an external magnetic field.

As a result, the induced Larmor precession in its electron orbits generates an opposing magnetic field, making bismuth one of the most diamagnetic elements known.

Additionally, its crystalline anisotropy causes variations in diamagnetism based on the field’s orientation relative to the atomic lattice, further emphasizing its structural dependence.
