Low-temperature specific heat study of antiferromagnetic transition in ternary rare-earth metal silicide R5Ir4Si10 (R = Tb, Dy, Ho, Er) Tsutsumi, Kitomi 672 20143323 20143323 Takayanagi, Shigeru 15611 Maezawa, Kunihiko 15612 Kitazawa, Hideaki 15613 We investigated antiferromagnetic transitions of R5lr4Si10 (R = Tb, Dy, Ho, Er) by measuring the low-temperature specific heat. The antiferromagnetic transition temperature TN is precisely determined. TN is l0.7 K for R = Tb, TN is 5.8 K for R = Dy, TN is 5.1 K for R = Ho and TN is 3.5 K for R = Er, respectively. These results suggest that the antiferromagnetic transition of the ternary rare-earth metal silicide R5lr4Si10 is dominated by the exchange interaction between R3+ ions like as the antiferromagnetic transitions in the ternary rare-earth metal compounds RCu2Ge2 (R = rare-earth metal). In addition, we report the upturn of the specific heat below 1.5 K observed for R = Tb and Ho. © 2006 Elsevier B.V.
