Thermal Expansion of Samarium, Neodymium, and Praseodymium in the Temperature Range 2 to 50 °K

Correlating Crystallography, Magnetism, and Electronic Structure Across Anhysteretic First-Order Phase Transition in Pr2In

“…Chemical potentials of the elements, μ (Pr) and μ (In) , were calculated using the reported experimental lattice parameters for Pr (space group P6 3 /mmc, a = 3.671 Å, c = 11.831 Å) 55 and In (space group I4/mmm, a = 3.254 Å, c = 4.947 Å). 56 We calculated total energy of Pr 2 In (E Pr In 2 ) using our experimental crystallographic data obtained at different temperatures.…”

Thermal and Elastic Properties of Rare‐Earth Metals

“…between 25 and 0.5 K. I t is found that above 2 K, all is positive and a 1 is negative and below 2 K, the signs of both 011 and 0111 are reversed. The volume coefficient av is negative up to 18 K. Tonnies [50]. The crystal structure of terbium and gadolinium has been investigated by Vorobev and co-workers [51, 521 between 120 and 300 K. These studies revealed that the magnetic transitions which occur in these metals cause the anomalous behaviour of the thermal expansion coefficients.…”
