Abstract
The morphology and magnetic properties of bulk and ball – milled Ho(Fe0.5Co0.5)3 intermetallic compounds were studied. The influence of the high energy ball – milling (HEBM) duration for the final size of particles and crystallites was confirmed by a variety of complementary measurement methods. The presence of the main PuNi3 type of crystal phase was confirmed for crystalline and as – milled samples. The emergence of a partly amorphous phase was confirmed at the end of pulverization (t = 80 h). The synthesis of nanostructured flakes with a thickness of less than 100 nm after applying HEBM for various time periods was confirmed. Additionally, the formation of agglomerates for the prolonged pulverization was evidenced. The non – linear variation of magnetic parameters across milling was observed. Furthermore, a slight exchange bias and deformation of hysteresis loops for as – milled powders was noticed. A quantitative analysis of XPS spectra at the end of grinding process indicates the probable coating of flakes by Fe/Co oxides the amount of which varies over ion etching.
