I want to use the permittivity tensor, but the comsol is not reading the tensor components.

Dear, I am trying to simulate the magneto-optic Kerr effect, using the relative permittivity tensor, as it is known, such a tensor has in our case, components outside the diagonal, these components are dependent on the magneto-optical constant and also the field. However, when I am measuring the reflectance as a function of the normalized magnetic field, we observe that the comsol is not reading correctly the elements of the tensor, that is, the reflectance is constant even with the variation of the field. Can you help me?

In the figure found attached, Q is the magneto-optical constant, and m is the normalized magnetization, that is, it assumes values between 0 and 1.

Thanks.
