The bixbyite framework as a platform for frustrated noncollinear magnetism: resolving the magnetic ground state of $\beta$-Fe${}_2$O${}_3$

Chenjun Tang, Ondřej Malina, Jiři Tuček +3

Magnetic behavior across Fe${}_2$O${}_3$ polymorphs varies widely despite identical chemistry, highlighting crystal architecture as a key determinant of exchange topology, magnetic ani…
