Electrodeposited Heusler alloy films with enhanced magneto-optical property

Ultrafast Spin Dynamics of Electrochemically Grown Heusler Alloy Films

“…But earlier attempts of electrochemical growth of Heusler alloy have shown limited success in achieving crystalline order as well as good morphological quality of the films. This may be due to the fact that these electrochemical growth processes have been carried out on polycrystalline metallic plates. − …”

Enhanced Magnetic Properties of Electrodeposited Co2FeSn Film with High Structural Order

“…All the above thin films prepared by electrodeposition technique used polycrystalline highpurity Cu as the substrate. 11,14,15,21 Recently, Karim et al 16 used single crystalline Pt/Ta/Si (111) substrate and found improvement in the crystalline quality of electrodeposited film as compared to earlier reports on polycrystalline Cu substrate. Though the use of polycrystalline Cu substrate yields cost effective CFS films, obtaining a fully ordered L2 1 type structure in electrodeposited CFS films has posed considerable challenge.…”

“…3,4 Tanaka et al 5 synthesized CFS thin films with ordered L2 1 structure for the first time by an atomically controlled deposition system. Subsequent to Yin et al 6 establishing the phase separation of molten CFS into Co 2 Sn 3 and FeCo phases using electron micrographs, several authors resorted to prepare this alloy in either nanoparticle, [7][8][9][10][11] nanowire 12,13 or thin film 11,[14][15][16] form. These experimental and first principles calculations [17][18][19][20] revealed some remarkable properties of CFS system such as soft magnetic nature, 7,8,[12][13][14][15] high magnetic moment, 1,3,4,7,8,14,[17][18][19] high Curie temperature, 13 high spin polarization, 13,17 tunable magnetic properties, 12 etc.…”

“…These studies indicate the strong potential of this alloy in magnetic recording, 8,13,14 magnetic driven sensors, 8 information devices, 14 spintronics, 12,13 and hyperthermia treatment of cancer. 11 Since the applicability of CFS in various fields demands an economic way to prepare it in thin film form, electrodeposition, which is a simple, non-equilibrium, cost effective, easily controllable, and easily scalable technique has caught the attention of researchers. Chisholm et al 21 were the first to synthesize Sn rich Co-Fe-Sn ternary alloy system using the electrodeposition technique.…”

“…Later, Lu et al 12 and Galdun et al 13 utilized the electrodeposition technique to prepare B2 type disordered CFS nanowires. Karim et al 11 successfully achieved B2 type disordered structure in CFS thin film and studied its magneto-optical Kerr effect. All the above thin films prepared by electrodeposition technique used polycrystalline highpurity Cu as the substrate.…”
