表现为两个突出的谷状体系,在退磁冷却过程中,中国科学院大学的苏刚和中国科学院物理研究所的孙培杰以及北京航空航天大学的金文涛等人合作并取得一项新进展, Ziyu, 中子衍射实验进一步证实了三亚晶格自旋固体有序共存和层间不可通约性,同时展现出零粘度的超流动性, with the lowest temperature attaining below 100mK. Not only is there an experimentally determined series of critical fields but the demagnetization cooling profile also shows excellent agreement with the theoretical simulations with an easy-axis Heisenberg model. Neutron diffractions also successfully locate the proposed spin supersolid phases by revealing the coexistence of three-sublattice spin solid order and interlayer incommensurability indicative of the spin superfluidity. Thus,他们揭示自旋超固体候选物Na2BaCo(PO4)2中的巨磁热效应,并为亚开尔文制冷的应用开辟了一条可行且有前途的途径,。
