One possible path forward is to exploit the duality between electric and magnetic dynamics expressed by Maxwell\u2019s equations. From this duality, one could naively expect mirror-like similarities in the behavior of electric and magnetic dipoles. However, a profound difference between the quantized lattice electric excitations\u2014such as phonons\u2014and spin excitations\u2014such as paramagnetic and antiferromagnetic spin resonances and magnons\u2014has now been unveiled in terms of their corresponding contributions to the static electric susceptibility and magnetic permeability. Viktor Rindert of Lund University in Sweden and his collaborators have derived and verified a formula that relates a material\u2019s magnetic permeability to the frequencies of magnetic spin resonances [1].<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A new formula that connects a material\u2019s magnetic permeability to spin dynamics has been derived and tested 84 years after the debut of its electric counterpart.
