Polycrystalline Ni–Mn–Ga thin films have been deposited by the pulsed laser deposition ~PLD! technique, using slices of a Ni–Mn–Ga single crystal as targets and onto Si ~100! substrates at temperatures ranging from 673 K up to 973 K. Off-stoichiometry thin films were deposited at a base pressure of 1310 Torr or in a 5 mTorr Ar atmosphere. Samples deposited in vacuum and temperatures above 823 K...
