N2 - The change in magnetic properties of La(Fe0.88 Al0.12)13 by hydrogenation has been investigated. The NaZn13-type structure is preserved and the lattice constant is increased after hydrogenation, showing that the hydrogen atoms intrude into the position between the icosahedral clusters and La atoms. By hydrogenation, the magnetic ground state is changed from the antiferromagnetic to the ferromagnetic state, accompanied by significant increases in the spontaneous magnetic moment and the Curie temperature.
