TLDR
Magnetic susceptibility measurements have been carried out on single and polycrystalline specimens of lutetium between 1.5 and 300 °K by the Faraday method as mentioned in this paper.Abstract:
Magnetic susceptibility measurements have been carried out on single and polycrystalline specimens of lutetium between 1.5 and 300 °K by the Faraday method. Its susceptibility was found to be paramagnetic and almost independent of temperature. A broad maximum centered at approximately 120 °K was found. Due to the discrepancies in past results of yttrium and lanthanum, their susceptibilities were also measured. Yttrium and lutetium were found to have χa greater than χc. Provided the specimens were of high purity, the relationship χpoly = (2/3)χa + (1/3)χ was well obeyed. Oxygen and hydrogen were found in general to lower the susceptibilities of these metals. The presence of an fcc phase in lanthanum was found to increase its susceptibility relative to a dhcp phase. An estimate of the susceptibility of pure fcc lanthanum is given.read more

Influence of hydrogen on the low temperature heat capacity of lutetium-rich lutetium-hydrogen alloys
TL;DR: In this article, the authors measured the low temperature (1-20K) heat capacity results of lutetium containing up to 15.%H in solid solution and found that the electronic specific heat constant, γ, initially increased by ∼35% when 1.5 at.% H was added, and then γ decreased at higher hydrogen concentrations.

Sc9Te2: A Two-Dimensional Distortion Wave in the Scandium-Richest Telluride
Paul A. Maggard,John D. Corbett +1 more
TL;DR: The structure of Sc9Te2 can be viewed as columns built either from distorted 3 × 3 bcc metal atoms or from distorted edge-sharing octahedra along a that are joined via intercolumn bonds on opposite sides into two-dimensional layers along b as discussed by the authors.

The Theory of Transition-Metal Ions
TL;DR: In this paper, the strong-filed coupling scheme was proposed to overcome the weak-field coupling scheme in paramagnetic resonance, which was shown to be effective in the case of free atoms and ions.

Progress in Low Temperature Physics
TL;DR: In this article, the specific heat of high-T c superconductors was studied. But the authors focused on the scaling of 3 He-4 He mixtures and did not consider the properties of the order parameter collective modes of these mixtures.

The Magnetic Susceptibilities of Lanthanum, Cerium, Praseodymium, Neodymium and Samarium, from 1.5°K to 300°K
TL;DR: The magnetic susceptibilities of the rare-earth metals lanthanum, cerium, praseodymium, naphase and samarium have been measured over the temperature range 1.5°K to 300°K, and it is believed that these metals become antiferromagnetic below these temperatures as discussed by the authors.
