Scaling of the magnetic entropy and magnetization in YbRh_2(Si_{0.95}Ge_{0.05})_2

P. Gegenwart, Y. Tokiwa, K. Neumaier +2

The magnetic entropy of YbRh_2(Si_{0.95}Ge_{0.05})_2 is derived from low-temperature ($T\ge 18$ mK) specific heat measurements. Upon field-tuning the system to its antiferromagnet…
