Magnetic properties of the borocarbides R3BxC4−x (R=Gd, Ho; x<1) with Sc3C4-type structure

The ternary RE–Si–B systems (RE=Dy, Ho, Er and Y) at 1270K: Solid state phase equilibria and magnetic properties of the solid solution REB2−xSix (RE=Dy and Ho)

“…Furthermore, the magnetization is fully reversible in decreasing field which proves that HoB 1.4 Si 0.6 is indeed a metamagnet. A similar alteration of magnetic ordering was previously reported for Ho 3 C 4−x B x (x < 0.8), but boron insertion in this case changes the pure binary antiferromagnetic carbide into a ferromagnetic compound [43].…”

Mn5Si3-type host-interstitial boron rare-earth metal silicide compounds RE5Si3: Crystal structures, physical properties and theoretical considerations

“…We note that the magnetic behavior is changed by boron insertion with respect to the pure binary phase: First only one magnetic transition is encountered, second the onset of ferromagnetic ordering is shifted to a higher temperature (Table 7). A similar behavior was earlier encountered upon boron insertion in the compound Ho 3 C 4Àx B x [38].…”

“…The boron insertion in binary compounds, e.g. Ho 3 C 4Àx B x [38], can establish pinning centers (magnetic hardening) or change the type of magnetic order AFM-FM. So the boron atoms in our case might simply act the same way.…”
