Effects of temperature and magnetic field on the spontaneous emission rate of polaron in a RbCl quantum rod qubit

Defect Engineering: Electron-Exchange Integral Manipulation to Generate a Large Magnetocaloric Effect in Ni41Mn43Co6Sn10 Alloys

“…Better still, even under a relatively small working field of 2 T, the ΔS M can still be maintained near 20.0 J/(kg K), which is higher than the values reported in other state-of-the-art Ni−(Co)−Mn−X-based Heusler alloys under the same magnetic field of 2 T, as shown in Figure 3f. To comprehensively assess the magnetocaloric performance of our irradiated sample, one homebuilt device in Northeastern University 34,35 is used to measure the adiabatic temperature variation ΔT ad , in which the temperature difference is visually reflected by the PT100 temperature sensor (adhered on the sample) in the process of inserting the sample into the magnetic field, followed by drawing the sample out. Similar to the measurement process of the M(H) curves, this testing also obeys the "Loop" method, that is, cooling the sample into the martensitic phase before heating to the next target temperature.…”
