Essential momentum dependence of the electron g-factor is a fundamental and, so far, largely overlooked property of antiferromagnetic conductors. I will discuss some of its experimental consequences. The predictions may be relevant to a number of antiferromagnetic conductors, ranging from chromium to electron- and hole-doped cuprates, borocarbides, pnictides, as well as organic and heavy fermion antiferromagnets.
