Table 1. Different dichroic contributions to the radiation-matter interaction.
The involved mixed terms of the radiation-matter interaction and their parity behaviour is listed for each type of dichroism. M stands for the sample magnetization. For the sake of completeness we recall that other dichroisms can be obtained with linearly polarized light. These are: X-ray linear dichroism, X-ray magnetic linear dichroism, which are both parity and time-reversal even, and non-reciprocal linear dichroism, which is parity odd and time-reversal odd.
| Parity | Time Reversal | ||
|---|---|---|---|
| XNCD | E1M1+E1E2 | − | + |
| XMCD | + | − | |
| XMχD | − | − |
