Ferromagnetic CrSb film fabricated by pulse-laser deposition and rapidly annealing

CrSb film was fabricated by pulse laser deposition (PLD) on Si (1 0 0) wafer. Strong ferromagnetism was observed in the CrSb film annealed at a high heating/cooling rate of 200 K/s, which can be attributed to the presence of ferromagnetic zinc blende (ZB) CrSb phase. The appearance of metastable ZB-CrSb results from the strong inner stress due to the precipitation of the monoclinic Sb.
