Structural, magnetic and electronic properties of FeRhxPd1-x compounds: Ab initio study

Correlation between magnetic and crystal structural sublattices in palladium-doped FeRh alloys: Analysis of the metamagnetic phase transition driving forces

“…According to experimental evidence, it is known that the B1 phase should be paramagnetic [27,38]. However, earlier the problem of the possibility of the ferromagnetic ordering of this structure was considered [41]. Therefore, the reasons for the observation of the paramagnetic state are still unclear.…”

“…The calculation of the paramagnetic phase was carried out in two ways. In the first case, a non-spin polarization model (NM) was used, just as it was done in the work [41].…”

“…In turn, the magnetic behavior of the -phase is also controversial. Despite a majority of experimental works reporting the paramagnetic state of the former at room temperature [27,38,40], there are theoretical works that predict the stable FM state of the equiatomic FeRh phase [41,42]. Moreover, in the experimental works [25,43] the spin-glass behavior of the phase in bulk alloys and nanoparticles with fcc crystal structure has been reported.…”
