Vpliv sinteznih pogojev na morfologijo in magnetne lastnosti SrFe[spodaj](12)O[spodaj](19) nanodelcev
Aleksander Učakar, Milan Bizjak, Petra Jenuš
Diplomsko delo
Oznake: strontij heksaferit;magnetni nanodelci;hidrotermalna sinteza;VSM;XRD;SEM;
V diplomskem delu smo raziskovali vpliv sinteznih pogojev na obliko, velikost in magnetne lastnosti stroncij heksaferitnih nanodelcev. Stroncij heksaferit (SrFe12O19) smo sintetizirali s hidrotermalno metodo, katere cilj je izboljšanje magnetnih lastnosti (nasičeno in remanentno magnetizacijo ter ko ...

Ferrite-based magnets by high pressure consolidation
C. De Julián Fernández, Blaž Belec, Aleksander Učakar, Petra Jenuš
Objavljeni povzetek znanstvenega prispevka na konferenci
Oznake: ferrite magnets;high pressure consolidation;low temperatures;
M-type hexaferrite magnets constitute together the rare-earth magnets the most employed magnets in the world. Even if ferrite magnets have smaller energy product and lower magnetization saturation than rare-earth permanent magnets (PMs), currently ferrite magnets represent the most widely used PMs ...
