利用介子自旋和小角中子散射对La1.9Sr0.1CuO4中涡旋态的阶数进行了探测。观察到从布拉格玻璃到旋涡玻璃的转变，其中旋涡玻璃由无序的旋涡线组成。在相变附近，微观行为反映了热诱导和钉钉诱导的混乱的微妙相互作用。
The order of the vortex state in La1.9Sr0.1CuO4 is probed using muon-spin rotation and small-angle neutron scattering. A transition from a Bragg glass to a vortex glass is observed, where the latter is composed of disordered vortex lines. In the vicinity of the transition the microscopic behavior reflects a delicate interplay of thermally induced and pinning-induced disorder.
