Magnetocaloric effect in metallic antiperovskite Mn3InC compound: Ab-initio study and Monte Carlo simulations

Revisiting the magnetic and magnetocaloric properties of bulk gadolinium: A combined DFT and Monte Carlo simulations

“…It must be mentioned that although Ab initio methods give fundamental information about different properties of systems, these methods still not capable to provide a description of systems at non-null temperatures. Therefore, the firstprinciple calculations (FPCs) at 0K of hcp bulk Gd within DFT schema are extended to the no zero-temperature MC method which is frequently applied in order to study a large number of strongly coupled degrees of freedom not only at the bulk solid [32][33][34][35] but also at the nanoscale [36,37].…”

Magnetic Field‐Oriented Electrical Transport Properties in Antiperovskite Mn3SnC

“…[21] Moreover, the phase transitions are usually accompanied by a magnitude of the entropy change, which is related to the amount of order that is lost or gained during this transition. [5][6][7][8][9][10][11] The IP field-oriented FMR of the 3 Â 5 mm 2 Mn 3 SnC film is shown in Figure 4. 10 GHz radio frequency (rf ) power was injected and subsequently absorbed, and the first derivation of the absorbance was presented as the FMR spectrum.…”

“…The procedure was repeated until a pure single phase was obtained. [ 8 ] After roughly cutting, the sample was precisely polished by a variety grit of sandpapers. Referring to the another study [ 20 ] and considering field dependence of longitudinal magnetoresistance mainly reflect the films’ surface magnetization which does not follow the corresponding bulk magnetization.…”

“…The ternary manganese compounds with a formula of Mn 3 MC (M = Al, Ga, Zn, In, and Sn) have the cubic crystal structure of an antiperovskite type: the Mn atoms on the cubic corners and the C atom centered in the unit with space group Pm m . The compounds usually have a wide variety of attractive effects, like giant magnetoresistance, [ 1 ] superconductivity, [ 2 ] negative thermal expansion, [ 3 ] and magnetocaloric effect, [ 4–8 ] at magnetic or temperature fields. These detectable macroscopic effects promote the materials to be the outstanding candidate for mature magnetic device applications.…”
