Materials Data on Pr2In by Materials Project

Pr2In crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. there are two inequivalent Pr sites. In the first Pr site, Pr is bonded in a 6-coordinate geometry to eight Pr and six equivalent In atoms. There are two shorter (3.51 Å) and six longer (3.69 Å) Pr–Pr bond lengths. All Pr–In bond lengths are 3.69 Å. In the second Pr site, Pr is bonded to six equivalent Pr and five equivalent In atoms to form a mixture of distorted face and corner-sharing PrPr6In5 trigonal bipyramids. There are three shorter (3.24 Å) and two longer (3.51 Å) Pr–In bond lengths. In is bonded in a 11-coordinate geometry to eleven Pr atoms.

First-order magnetic phase transition in P r 2 In with negligible thermomagnetic hysteresis

Magnetic first-order phase transitions are key for the emergence of functionalities of fundamental and applied significance, including magnetic shape memory as well as magnetostrictive and magnetocaloric effects. Such transitions are usually associated with thermomagnetic hysteresis. In this paper we report the observation of a firstorder transition in Pr 2 In from a paramagnetic to a ferromagnetic state at $T_C$ = 57K without a detectable thermomagnetic hysteresis, which is also accompanied by a large magnetocaloric effect. The peculiar electronic structure of Pr2In exhibiting a large density of states near the Fermi energy explains the highly responsive magnetic behavior of the material. The magnetic properties of Pr 2 In are reported, including observation of another (second-order) magnetic transition at 35 K.
