Studies of light-induced demagnetization started with the experiment performed by Beaupaire et al. on Ni. Here, we present theoretical predictions for X-ray induced demagnetization of nickel, with X-ray photon energies tuned to its \(M_3\) and \(L_3\) absorption edges. We show that the specific feature in the density of states in the d-band of Ni, i.e., a sharp peak located just above the Fermi level, strongly influences the change of the predicted magnetic signal, making it stronger than in the previously studied case of X-ray demagnetized cobalt. It impacts also the value of Curie temperature for Ni. We believe that this finding will inspire dedicated experiments investigating magnetic processes in X-ray irradiated nickel and cobalt.

光致退磁的研究始于 Beaupaire 等人进行的实验。在尼.在这里，我们提出了 X 射线诱导镍退磁的理论预测，其中 X 射线光子能量调整到其\(M_3\)和\(L_3\)吸收边。我们表明，Ni d带中态密度的特定特征，即位于费米能级上方的尖峰，强烈影响预测的磁信号的变化，使其比之前研究的情况更强X射线消磁钴。它还影响镍的居里温度值。我们相信，这一发现将激发专门的实验研究 X 射线照射的镍和钴的磁性过程。
