Experiments on Magnetic Superfluid State of Liquid Helium-3

提出了9510306个小岛实验，以探索超低温和强磁场下液态He-3磁性超流A-1相的性质。A-1相的温度宽度将通过研制声学温度计来测量。超流分数将使用自旋/熵波传播技术进行测量。自旋弛豫将由一种新型的机械装置来测量，以检测自旋密度。所有这些测量都被提议从我们之前的最大5特斯拉扩展到15特斯拉。液态氦-3的温度将降至0.001开尔文，磁场高达150,000高斯。在这些条件下，液态氦-3转变成一种独特的磁性超流状态。研究的重点将是测量超低温下磁极化对超流态的影响。在拟议的实验中，将使用声学和机械设备来研究热力学、流体力学和磁性。对超流状态的更好理解可能被用于研究更常见的金属超导态。***

9510306 Kojima Experiments are proposed to explore the properties of the magnetic superfluid A-1 phase of liquid He-3 at ultra low temperatures and in high magnetic fields. The temperature width of the A-1 phase will be measured by developing an acoustic thermometer. The superfluid fraction will be measured using spin/entropy wave propagation techniques. The spin relaxation will be measured by a novel mechanical device to detect spin density. All of these measurements are proposed to be extended from our previous maximum field of 5 tesla up to 15 tesla. %%% Liquid Helium-3 will be subjected to temperatures down to 0.001 degrees Kelvin and to magnetic fields as high as 150,000 gauss. Under these conditions, liquid Helium-3 transforms into a unique magnetic superfluid state. The focus of research will be to measure the effects of the magnetic polarization on the superfluid state at ultra low temperatures. Thermodynamic, hydrodynamic and magnetic properties will be investigated using acoustic and mechanical devices in the proposed experiments. Better understanding of the superfluid state might be applied to studies of more familiar superconducting states of metals. ***
