Tailoring the ferrimagnetic-to-ferromagnetic transition field by interstitial and substitutional atoms in the R-Fe compounds

Popis výsledku v původním jazyce

Magnetic properties of rare-earth compounds R2Fe14B are highly sensitive to atomic substitutions and interstitial absorption of light elements. We studied a combined influence of the substitutions in the R sublattice and hydrogen absorption on the behavior in field up to 60 T. For R = Er and Tm it was shown that substitution of Nd for Er or Tm increases the saturation magnetization as a result of ferromagnetic ordering of Nd and Fe moments. Under sufficiently high field the magnetic moments rotate and the field-induced ferromagnetic state may be observed. The field at which a transition occurs is related to the strength of the inter-sublattice exchange interaction. The role of hydrogen is primarily to weaken the inter-sublattice ferrimagnetic coupling so the reorientation becomes achievable at the available magnetic field in hydrides Tm2Fe14BH5.5 and (Tm0.5Nd0.5)2Fe14BH5.5.
