Three-dimensional solids in the limit of high magnetic fields
... these very high fields is also reviewed. It is explained how diamagnetic and Pauli pair breaking are avoided, and why materials which are not superconducting at low temperature may be superconducting at high fields. The possibility of triplet superconductive pairing is considered. The suggested prop ...

... From the figure, we see that the minimum intensity is zero, and occurs when cos φ = −1/ 2 . The condition for primary maxima is cos φ = +1 , which gives I / I 0 = 1 . In addition, there are also secondary maxima that are located at cos φ = −1 . The condition implies φ = (2m + 1)π , which implies tha ...
