Magnetoelastic coupling associated with the hexagonal—monoclinic transition in a natural
sample of the mineral pyrrhotite, Fe 7 S 8, has been analysed in terms of separate coupling …

Pyrrhotite Fe 7 S 8 provides an example of exceptionally strong magnetoelastic coupling
through pinning of ferromagnetic domains by ferroelastic twins. Using direct imaging of …

The properties of the selenide compound Fe 7 Se 8 with a layered crystal structure of the
NiAs type are strongly influenced by substitutions and the distribution of vacancies. The Cr …

The magnetic properties of trigonal 3C Fe7S8 nanoparticles, synthesized via the thermal
decomposition method, are investigated using temperature-dependent zero-field cooled …
