Ferromagnetic and antiferromagnetic ordering in platinum-manganese alloys: low-temperature specific heat. Journal of Temperature Physics. 17(5), s. 425-438.https://www.springer.com/journal/10909https://hdl.handle.net/20.500.12415/3213Measurements are reported of the specific heat of a number of PtMn alloys. Interaction between the manganese impurities gives rise to antiferromagnetic or ferromagnetic ordering depending on the impurity concentration, the critical concentration for ferromagnetism being 0.8 at % Mn. Using the effect on the specific heat anomaly of the statistical fluctuations in the number of the impurities in a given volume, the interaction range of the impurities is estimated and found to agree with the band structure of platinum.eninfo:eu-repo/semantics/closedAccessArticle438542517
