Magnetism of light actinides exhibits fascinating and potentially useful features. One of them is a giant anisotropy of the two-ion type, apparent mostly in U-based systems. Here we demonstrate on the example of U2Ni2Sn and its hydride the anisotropy switches over the direction of U moments on a very fine scale. The study of amorphous sputter deposited UFex films reveals how the Curie temperature can be tuned so as to exceed the room temperature.
