Ni–Mn–Ga thin films produced by pulsed laser deposition

Investigation of Magnetite Thin-Films Produced by Pulsed Laser Deposition

Thin-films of magnetite, F@04 have been produced by the XeCl excimer laser ablation of both Fe304 and metallic Fe targets. The ablation of metallic Fe has been shown to produce about two orders of magnitude smaller concentration of boulders than the ablation of bulk magnetite. The use of single-crystal, latticematching substrates was found to be necessary at lower fluences (1 3 J cm-') for the ...

Ni–Mn–Ga thin films produced by pulsed laser deposition

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...

Pulsed laser deposition of VO2 thin films

High quality vanadium dioxide ~VO2! thin films have been successfully deposited by pulsed laser deposition without postannealing on ~0001! and ~101̄0! sapphire substrates. X-ray diffraction reveals that the films are highly oriented with ~010! planes parallel to the surface of the substrate. VO2 thin films on ~0001! and ~101̄0! substrates show semiconductor to metal transistions with electrical r...

Boron films produced by high energy Pulsed Laser Deposition

Micron-thick boron films have been deposited by Pulsed Laser Deposition in vacuum on several substrates at room temperature. The use of high energy pulses (>700 mJ) results in the deposition of smooth coatings with low oxygen uptake even at base pressures of 10 -4 -10 -3 Pa. A detailed structural analysis, by X-Ray Diffraction and Raman, allowed to assess the amorphous nature of the deposited f...
