Sign conventions in magneto-optical calculations and measurements

Area of Science:

• Physics
• Optics
• Magnetism

Background:

• Magneto-optical effects are crucial in various scientific and technological applications.
• Inconsistent sign conventions in the literature complicate the understanding and comparison of experimental and theoretical magneto-optical data.

Purpose of the Study:

• To outline the multiplicity of sign conventions in magneto-optics.
• To identify and compare the two primary schemes used for describing magneto-optical effects.
• To recommend a preferred sign convention for consistent reporting.

Main Methods:

• Literature review of theoretical and experimental studies on magneto-optics.
• Analysis of sign conventions used in describing magneto-optical phenomena.
• Comparative assessment of different sign convention schemes.

Main Results:

• There are multiple, often competing, sign conventions in the magneto-optics literature.
• Two main schemes for describing magneto-optical effects exist, with subtle but important differences.
• A specific preferred scheme is identified and justified for adoption.

Conclusions:

• Standardizing sign conventions in magneto-optics is essential for clarity and reproducibility.
• Adopting the recommended scheme will enhance the consistency of theoretical and experimental reporting.
• This work provides a basis for unified communication in the field of magneto-optics.
