Аннотация:Magnetic characteristics of the Nd2Fe14BHx single crystals and polycrystalline samples were investigated in the temperature range 4.2-750 K. It is established that hydrogen absorption does not change the crystal structure of these compounds but is accompanied by an expansion of a unit cell volume. The obtained data show that the Curie temperature and magnetic moment are increasing in the all investigated hydrides whereas the temperatures of a spin-reorientation transition remain unchanged.
