Microstructure and stripe domains in Ni–S ferromagnetic thin films

Effect of Co substitution for Ni on the microstructure and magnetic properties of (Fe, Ni)-based amorphous alloys produced by melt spinning

“…The stripe orientation is forced along the bulk magnetization direction by exchange coupling. Assuming a model of stripe domain nucleation like in thin films [24,21], the thickness of the free surface zone with perpendicular anisotropy can roughly be estimated to about 0.5 lm, corresponding to the width of the stripe domains. The stripe-shaped domains presented in Figs.…”

“…The saturation magnetization and the effective anisotropy constant of the thin ribbons were determined with a computer-assisted torque-magnetometer (CATQM) in an external DC magnetic field up to 480 kA/m at room temperature [21]. The magnetic domain structure was studied by powder patterns method (Bitter technique) and imaged by using a high-sensitivity video camera mounted on the ocular site of an optical microscope and by using a video processor [22].…”

Effect of annealing temperature and rate of sputtering on the magnetic properties and microstructure of the polycrystalline nickel films with (200) texture

“…It is known from [20][21][22][23][24] that the SDS is formed in the ferromagnetic films whose thickness is greater than critical thickness d cr , which depends on the film mate rial [4,23], chemical composition [17,22], substrate temperature during the film growth [20], and anneal ing temperature [3]. The presence of SDS indicates the existence of the perpendicular magnetic anisot v v ropy (PMA) [17,21].…”
