These optical elements have a large Verde constant V (physical quantity that characterizes the magnetic rotation of the plane of polarization in the material), which connects the value of the integral of the magnetic field Н, taken across the length of the optical path L, and the angle of the plane of linearly polarized light ΔФ, transmitted through the optical circuit: (1) This angle ΔФ is also equivalent to nonreciprocal phase shift of a circularly polarized wave transmitted through a fiber loop.
