摘要: Magnetic properties as well hyperfine interactions in Ti(Fe, -xCo,) and some of its hydrides have been studied. With the concept antistructure (AS) atoms proposed recently by Brommer et al. two critical concentrations at x = 0.25 0.65, correlation between iron field bulk magnetisation concentration dependence can be explained consistently. A pattern with a 23.5 T (corresponding to value 1.5 pR) presents direct experimental evidence for presence AS atoms. These, together an increasing N (E F ) cobalt grows. are supposed influence onset long-range magnetic order. Furthermore i t is suggested that, upon hydrogen absorption, additional created, it these, rather than surface segregations which responsible change 2 phase Ti(Fe,Co) hydrides.
