Nuclear Magnetic Resonance and Magnetic Susceptibility of Pr3Al11, Nd3Al11, and EuAl4

Abstract
The Knight shifts of the 27Al NMR in Pr3Al11, Nd3Al11, and EuAl4 have been measured between 86 and 300°K, and have been found to be different for inequivalent Al sites. The results are discussed in terms of the Ruderman–Kittel–Kasuya–Yosida theory. The magnetic susceptibilities have been measured in the temperature region from 300 down to 4.2°K, and found to deviate from Curie–Weiss laws only for temperatures lower than 40°K.
