Laser pulses trigger two-step type-II demagnetization in the MAX phase (Cr0.5Mn0.5)2GaC, a signature of its two-dimensional magnetic order.

Claims

C1strongest claim

the demagnetization transients exhibit a two-step type-II demagnetization - a signature of two-dimensional magnetic systems. The reconstructed spin heat capacity exhibits a weak temperature dependence, accounting for the absence of significant slowing down of demagnetization at elevated temperatures and fluences.

C2weakest assumption

That the observed two-step transients are a direct signature of two-dimensional magnetism and that the three-temperature model fully captures the dynamics without additional channels or material-specific corrections.

C3one line summary

First observation of two-step type-II ultrafast demagnetization in (Cr0.5Mn0.5)2GaC MAX phase film below 250 K, with three-temperature model yielding electron-lattice, spin-lattice and electron-spin couplings and a weakly temperature-dependent spin heat capacity.
