Specific heat of an epoxi resin below 1 K

The specific heat as a function of temperature of Stycast 1266 was measured in the range from 0.1 to 1 K. The results are described, within 2%, by the expression c(T)=aT+bT 3+cT 5, where a=2.91(6) μJ/g K2, b=15.7(5) μJ/g K4, and c=8.98(0) μJ/g K6. The linear and cubic terms were related to the model...

Description
Summary:The specific heat as a function of temperature of Stycast 1266 was measured in the range from 0.1 to 1 K. The results are described, within 2%, by the expression c(T)=aT+bT 3+cT 5, where a=2.91(6) μJ/g K2, b=15.7(5) μJ/g K4, and c=8.98(0) μJ/g K6. The linear and cubic terms were related to the model of two‐level systems and to the Debye specific heat, respectively. The origin of the T 5 contribution remains unexplained.
