| 简介 |
The present invention refers to 4 made both elements of the rare earth metal photographic printRELixCu2-yP2 (RE=La, Pr, Nd, Gd, Er; 0. X 82 ≤ ≤ 1; 0. Y 46 ≤ ≤ 0. 81) a wherein in number, each hot reaction by mixing the starting material can be synthesis of. Synthetic compounds are group space-based gray level by repressing third voltage in 3 Which belonging to, crystal structure, designatedCaAl2Si2Li to type structures is form is filled, two anion atoms Li (P and a Cu) 2 formed by in between the constitution : is partially filled with. PrLi 0. 98 (5) Cu 1. 54 (1) P 2. 82, via a compoundθP=-6. 8 K arranged antiferromagnetically Pr in identifying corresponding advertisement based on the shown list 323 K (antiferromagnetic ordering) that no temperature gradients occur inside the thermal conductivity in 3. 2 W/mK randomly choosing has been confirmed. |
