The dynamics of spontaneous hydrogen segregation in LaFe${}_{13-x}$Si${}_x$H${}_y$

Oliver L. Baumfeld, Zsolt Gercsi, Maria Krautz +2

By means of time- and temperature-dependent magnetization measurements, we demonstrate that the timescale of hydrogen diffusion in partially-hydrogenated LaFe${}_{13-x}$Si${}_x$H${}_y$ i…
