New Heat-Capacity Measurements of the Possible Order-Disorder Transition
in the 4/7-phase of 2D Helium [PDF]
S. Nakamura, K. Matsui, T. Matsui, Hiroshi FukuyamaWe have developed a new heat-capacity measuring system with ZYX graphite that is known to have much better crystallinity than Grafoil and started data collection. We report preliminary data as well as a detailed description of instrumentation including a mechanical heat-switch operated by hydraulic pressure of superfluid helium-4.View original: http://arxiv.org/abs/1210.0391
