Corrigendum to “Synthesis and characterization of the heavy-fermion compound CePtAl<inf>4</inf>Ge<inf>2</inf>” [J. Alloys Compd. 738 (2018) 550–555] (Journal of Alloys and Compounds (2018) 738 (550–555), (S0925838817343761), (10.1016/j.jallcom.2017.12.180))

The authors regret that the printed version of the above article contained a number of errors. The correct and final version follows. The authors would like to apologise for any inconvenience caused. In this corrigendum, we clarify crystallographic data so that it complies with conventions of Pearson's database, correct some of those data, provide corrected magnetic susceptibility and magnetization data for CePtAl4Ge2 and correct typographical errors. List of corrections 1. Correcting typos in the caption of Fig. 2. On the 2nd line from the top of the caption of Fig. 2, the legend for (a) should be corrected: “… for the magnetic field of 1 kOe applied parallel (χc, open triangles) and perpendicular to the crystallographic c-axis (χab, open circles).” 2. Revision of Table 2. The atomic coordinate z is revised to fix errors and labels on Al sites are modified to conform to the Pearson's database. 3. Revision of Table 3 and 4 The labels on Al sites are modified to conform to Pearson's database. [Table presented] [Table presented] 3.1. In page 551, on the 3rd line from the top of the caption of Fig. 1, the label of the Al should be modified from Al(1) to Al(2). 3.2. In page 552, on the 4th line from the bottom of the 1st paragraph in the ‘3.1. Crystal structure’, the label of the Al should be modified from Al(1) to Al(2). [Table presented] 4. Revision of Figs. 2(a), (b) and the Curie-Weiss fitting parameters. Our recent study of the magnetic properties of much larger, high-quality single crystals of CePtAl4Ge2 have revealed reproducible differences compared to those reported in Shin et al. JAC 738, 550 (2018). These differences arise from now a much larger intrinsic signal to background response and improvements in measurement techniques. Results from a much larger crystal, plotted in Fig. 2 below, are compared to previously published results in Table e1. [Table presented] 4.1. On the 4th line from the bottom of the last paragraph in the Material and Methods part, the description on the temperature range should change from 350-1.8 K to 300–1.8 K: ‘ … at a magnetic field of 1 kOe over a temperature range of 300–1.8 K’. 4.2. The sentence on the 8th line from the top of the 2nd paragraph in the section ‘3.2. Magnetic susceptibility’ should change to “The dependence on temperature of χ is well explained by the Curie–Weiss law χ = χ0 + C/(T − θCW) for temperatures higher than 250 K, where χ0 = 0.00042 and 0.00053 emu/mol for χab and χc, respectively. The red solid lines are fits that give an effective magnetic moment (μeff) of 2.51 and 2.50 μB for χab and χc, respectively. The averaged polycrystalline value for a trigonal structure, μpoly = [1/3(μc)2+2/3(μab)2]1/2, is 2.51 μB which is close to the theoretical value, 2.54 μB, of free Ce3+ ions. The Curie–Weiss temperature θCW estimated from fitting data above 250 K is 37.51 and −101.78 K for χab and χc, respectively.” 4 3. Results from the large crystal ae given in Figs. 2(a) and (b) and the caption of this figure is revised accordingly: [Figure presented]
