Specific heat of YMn2H and HoMn2H

Structural and magnetic properties of C15 HoMn2 hydrides

“…The results and discussion of the SH measurements of the HoMn 2 H x are reported in [30]. It is interesting to compare them with the results presented above.…”

“…RMn 2 H 1.0 , T N ∼ 200 K), which was confirmed above by the magnetic and X-ray measurements. For example, the broad maxima of C mol (T) for the x = 1.0 and 1.65 hydrides between ∼170 and 250 K [30] are located in the same temperature range where both the structural (monoclinic → rhombohedral → cubic) and magnetic transformations are observed (Figs. 3-7, Table 2).…”

“…That is why the SH values rise with increasing hydrogen concentration. The temperatures at which hydrogen ordering is expected are underlined (T s column in Table 2 [30]). Also for higher hydrogen concentration, the transformations and characteristic temperatures (especially magnetic ones) are reflected in C mol (T) curves and their maxima.…”
