在这里，我们审查的正常和超导状态的铁基超导体使用强磁场的性质的测量。我们讨论了各种物理机制，限制超导在高场，和超导状态的信息，可以从上临界场提取，但也如何热波动影响其确定电阻率和比热测量。我们还讨论了正常态电子结构的测量，重点是量子振荡的测量，特别是de Haas-van Alphen效应。这些结果非常精确地确定了费米面的拓扑结构和一些不同的铁基超导体的准粒子质量，从1111，122和111家庭。
Here we review measurements of the normal and superconducting state properties of iron-based superconductors using high magnetic fields. We discuss the various physical mechanisms that limit superconductivity in high fields, and the information on the superconducting state that can be extracted from the upper critical field, but also how thermal fluctuations affect its determination by resistivity and specific heat measurements. We also discuss measurements of the normal state electronic structure focusing on measurement of quantum oscillations, particularly the de Haas–van Alphen effect. These results have determined very accurately, the topology of the Fermi surface and the quasi-particle masses in a number of different iron-based superconductors, from the 1111, 122 and 111 families.
