Curie temperature of nickel
WebMar 21, 2024 · The control of the spontaneous formation of nanostructures at the surface of thin films is of strong interest in many different fields, from catalysts to microelectronics, because surface and interfacial properties may be substantially enhanced. Here, we analyze the formation of nickel oxide nanocuboids on top of La2Ni1−xMn1+xO6 double … WebA previously developed microscopic theory for the wavevector-dependent spin susceptibility chi (q) of paramagnetic iron based on the Hubbard-Hasegawa approach has been applied to nickel. The equal-time spin-spin correlation function evaluated with the use of the calculated chi (q) and the classical fluctuation-dissipation theorem accounts well for the observed …

WebJun 15, 2024 · It was shown that the heating rate affects the recorded Curie temperature. Thus, with an increase in the heating rate from 1 to 50 K min −1, the Curie temperature increases from 356.7 to 360.9 °C. However, the obtained values correspond to the literature data of the Curie temperature for nickel. WebFor compounds with Ni, on the other hand, no magnetic moment at the nickel atoms is observed, and the magnetic interaction involves only the R sublattice [9,10]. Hence, these compounds are magnetically ordered at relatively low temperatures that reach even below 40 K with the exception of GdNi 2, where the Curie temperature is equal to 75 K .
