Covalency and vibronic couplings make a nonmagnetic j=3/2 ion magnetic

Lei Xu, Nikolay A. Bogdanov, Andrew Princep +3

For 4$d^1$ and 5$d^1$ spin-orbit-coupled electron configurations, the notion of nonmagnetic j=3/2 quartet ground state discussed in classical textbooks is at odds with the observed…
