Magnetic Drum – History of Magnetic Drum Memory

Magnetic Drum – History of Magnetic Drum Memory. Magnetic Drum. First magnetic drum memory, a magnetic data storage device and an early form of computer memory, which plays an important role in the computer memory development (e.g. used in ABC computer) and was widely used in the 1950s and into the 1960s, was invented by the Austrian engineer Gustav Tauschek (1899-1945) in 1932 in Austria.

Magnetic second-harmonic generation from interfaces and ...

2010-5-1  Nonlinear magnetic second-harmonic generation (MSHG) is a more difficult and expensive technique but, uniquely, can measure the surface and interface magnetism of centrosymmetric magnetic films with sub-monolayer sensitivity. MSHG is briefly reviewed and examples from high symmetry interfaces and nanostructures described.

What is Magnetic Drum? Webopedia

2001-4-24  A direct-access, or random-access, storage device. A magnetic drum, also referred to as drum, is a metal cylinder coated with magnetic iron-oxide material on which data and programs can be stored. Magnetic drums were once used as a primary storage device but have since been implemented as auxiliary storage devices.

Second-Harmonic Generation from Magnetic Metamaterials ...

2006-7-28  Abstract. We observe second-harmonic generation from metamaterials composed of split-ring resonators excited at 1.5-micrometer wavelength. Much larger signals are detected when magnetic-dipole resonances are excited, as compared with purely electric-dipole resonances. The experiments are consistent with calculations based on the magnetic component ...

OSA Experiments on second- and third-harmonic generation ...

Here, we present our experiments on second- and third-harmonic generation from magnetic metamaterials composed of nanoscale gold split-ring resonators and from control samples for excitation with 170-fs pulses centered at 1.5-μm wavelength. The strongest nonlinear signals are found for resonances with magnetic-dipole character.

2010-12-31  We present the second generation of the GFZ Reference Internal Magnetic Model (GRIMM-2), that was derived for the preparation of the GFZ candidate for the 11th generation of the IGRF. The model is built by fitting a vector data set made of CHAMP satellite and observatory data, spanning the period 2001.0 to 2009.5. The data selection technique and the model parametrization are similar to
