Dissipative heat and exchange dispersion on metastability of Gd5Si4

Atomically precise self-organization of perfectly ordered gadolinium–silicide nanomeshes controlled by anisotropic electromigration-induced growth on Si(1 1 0)-16 × 2 surfaces

“…Recently, several Gd silicides (e.g., GdSi, Gd 5 Si 4 Gd 5 Si 3 , and GdSi 5 ) have been reported to exhibit exotic magnetic properties [40][41][42][43][44], due to the exchange interaction between localized 4f electrons, which is mainly mediated by conduction electrons. In particular, the magnetocaloric material Gd 5 Si 4 shows magnetic ordering at 70 • C and has a high magnetic moment of eff = 9.6 B [41][42][43].…”

“…In particular, the magnetocaloric material Gd 5 Si 4 shows magnetic ordering at 70 • C and has a high magnetic moment of eff = 9.6 B [41][42][43]. Thus, by depositing the proper Gd coverage on a doubledomain Si(1 1 0)-16 × 2 surface, a self-ordered magnetic nanomesh, comprising two kinds of magnetic Gd-silicide NWs with various Gd concentrations (e.g., horizontal Gd 5 Si 4 NWs and oblique GdSi 5 NWs), can be obtained via the anisotropic electromigrationinduced 2D self-ordered growth.…”
