Sb-5$p$-mediated antiparallel Nd-Fe coupling in Nd${}_3$Fe${}_3$Sb${}_7$

S. Palazzese, Sh. Yamamoto, T. Kotte +15

We uncover the microscopic mechanism underlying the antiparallel Nd-Fe coupling in the intermetallic 4$f$-3$d$-5$p$ compound Nd${}_3$Fe${}_3$Sb${}_7$ by means of high-field x-ray magneti…
