摘要

在本研究中，我们对Hansa Devi等人之前发表在Journal of Physics and Chemistry of Solids 76(2015) 70-81上的文章进行了评论。在深入审查了他们的文章之后，我们发现他们的晶体密度（ρ）、纵向（Vl）、横向（Vt）、平均声波速度（Vm）以及二元金属间化合物的德拜温度（ϴD）数据的理论证据在很大程度上存在一些数值上的缺陷。由于这些扰动，Hansa Devi et el (Hansa et al., 2015) bbb。请注意改进他们的工作。因此，我们建议仔细改进他们的工作，消除这些参数中的数值误差，通过使用正确的公式重新计算所有数据，依赖于他们的出版物（Hansa et al., 2015）[1]中的晶格常数和刚度常数（Cij: C11, C12, C44）。

Remark on Hansa Devi et al.: “Electronic and high pressure elastic properties of RECd and REHg (RE = Sc, La, and Yb) intermetallic compounds” [J. Phys. Chem. Solid. 76 (2015) 70–81]

In the present study, we comment on the article previously published by Hansa Devi et al. in the Journal of Physics and Chemistry of Solids 76 (2015) 70–81. After reviewing their article deeply, we found some imperfections numerically on a very large scale in their theoretical evidence of crystal density (ρ), longitudinal (V_l), transverse (V_t), average acoustic wave velocities (V_m) and hence of the Debye temperature (ϴ_D) data for binary intermetallic compounds. Due to these perturbations, Hansa Devi et el (Hansa et al., 2015) [1]. give me attention for improving their work. Therefore, we have proposed to improve their work carefully on eliminating the numerical errors in such parameter by re-computing all data again by employing the correct formula depends upon the lattice constant and stiffness constants (C_ij: C₁₁, C₁₂, C₄₄) in their publication (Hansa et al., 2015) [1].

期刊介绍： The Journal of Physics and Chemistry of Solids is a well-established international medium for publication of archival research in condensed matter and materials sciences. Areas of interest broadly include experimental and theoretical research on electronic, magnetic, spectroscopic and structural properties as well as the statistical mechanics and thermodynamics of materials. The focus is on gaining physical and chemical insight into the properties and potential applications of condensed matter systems. Within the broad scope of the journal, beyond regular contributions, the editors have identified submissions in the following areas of physics and chemistry of solids to be of special current interest to the journal: Low-dimensional systems Exotic states of quantum electron matter including topological phases Energy conversion and storage Interfaces, nanoparticles and catalysts.
