英文摘要
We develop a novel method for refrigeration using helium isotope mixture liquid(^3He-^4He) in nanoporous media, and study the spintronic properties of helium-3 quasiparticles. Porous alumina substrates in which the pore size is narrowed by plating gold are successfully prepared. Measurements of superfluid properties of confined liquid^4He showed the reduction of pore size down to 10 nm. We pursue these methods to decrease the pore size down to 5 nm, at which the energy quantization of^3He quasiparticles and refrigeration are expected.
