High pressure magnetization and Curie temperature measurements have been performed on several amorphous Y,Ni,-, alloys. The results seem to indicate that ferromagnetism disappears in a rather inhomogeneous way.
Recent theoretical work for Ga1−xMnxN predicts ferromagnetism in this materials system with Curie temperatures above room temperature. Ferromagnetic behavior observed in Ga1−xMnxN is still controversial, as there are conflicting experimental reports owing to the disparity in c
High-pressure properties of MnPS$_3$ are investigated by using the hybrid functional, we report a spin-crossover pressure 35 GPa consisting with experimental observation (30 GPa), less than half existing (63 GPa) Hubbard U correction. Interestingly, induced antiferromagnetism-to-ferromagnetism transition combined stacking-order change from monoclinic to rhombohedral founded, and ferromagnetism ...
A systematic investigation of the microscopic conditions stabilizing itinerant ferromagnetism of correlated electrons in a single-band model is presented. Quantitative results are obtained by quantum Monte Carlo simulations for a model with Hubbard interaction U and direct Heisenberg exchange interaction F within the dynamical mean-field theory. Special emphasis is placed on the investigation o...
