In science:

In this letter we present for the first time an approach to predict the influence of magnetic order on optical phonons from first-principles and apply this approach to the strongly geometrically frustrated spinel zinc chromite.
Magnetic-induced phonon anisotropy in ZnCr$_2$O$_4$ from first principles
As a result, zinc chromite is strongly geometrically frustrated as evidenced by the rather low TN = 12.5K (compared to ΘCW ).
