Hard Magnetic Thin Films
Hard magnetic films have a broad application area ranging from magnetic recording media to microelectromagnetic devices. A challenge for recording media is the 60% annual increase in areal density, which requires ever smaller magnetic dots. However, for a given magnetic anisotropy the reduction of dot size is limited, since below a critical magnetic volume the magnetisation becomes thermally un...
متن کاملMagnetic cobalt nanowire thin films.
Two-dimensional (2D) and three-dimensional (3D) magnetic cobalt nanowire thin films with tunable 3-10 nm wire diameters have been electrodeposited using mesoporous silica templates containing 2D hexagonal or 3D cubic pore channels. As compared to bulk cobalt films, the cobalt nanowire thin films exhibit enhanced coercivities and controllable magnetic anisotropy through tuning of the mesostructu...
متن کاملSpatially modulated magnetic structures in thin films
The axial next–nearest neighbour Ising (ANNNI) model is studied for thin films of up to L = 10 layers, with a distinct phase diagram for each film thickness. The systematics of the ordered phases, as obtained from mean–field theory, Monte Carlo simulations, and low temperature expansions, is discussed. Results are compared to those for the ANNNI model in the limit L −→ ∞. PACS numbers: 68.35.Rh...
متن کاملNanosecond switching in thin magnetic films
A special pulse equipment including a pulse-sampling oscilloscope with an over-all response time of 0.35 nanosecond sec) for the observation of the nanosecond flux change in thin permalloy films is described. Film switching signals a s short a s 1 nanosecond have been obtained and are discussed with respect to the underlying processes. Inverse switching time versus driving-field curves have bee...
متن کاملMillimicrosecond Magnetization Reversal in Thin Magnetic Films
From ferromagnetic resonance xperiments and from calculations based on the modified Landau-Lifschitz equation, switching times for the coherent rotation of the magnetization in thin, permalloy-type films have been predicted to lie in the range of 1 mi1limicrosecond.l First measurements by D. 0. Smith et a1,2 utilizing a travellingwave oscilloscope with a response time of 2 mpec, indicated swi...
