Coercive Properties of Magnetic Garnet Films

چکیده

Magnetic garnet films represent a wide family of materials. By the proper choice chemical composition and growth parameters, their magnetic behavior can be tuned in very range. On one side, they are suitable for many different applications; on other optimal model materials studying basic magnetization processes. Many assumptions existing theories checked or validated by film investigation. Their production technology was developed decades ago, but even nowadays, have been intensively studied, newer application possibilities found. In this review paper, those results summarized, which connected with coercive properties. Coercivity, force, is frequently used characteristic, usually, it considered rather technical parameter. It shown that there no correlation between so-called “technical force” (which half-width major hysteresis loop) domain wall coercivity (this called pinning field). This latter parameter real characteristic movement. If investigated, moving material defect structure studied. complex feature shown. demonstrated structure, properties walls, existence mechanical stresses, temperature, size sample parameters an influence measured coercivity.

Epitaxial Magnetic Garnet Heterostructures

A summary of our recent progress in the growth and characterization of magnetic and magnetooptic garnet heterostructures is presented in this paper. The similarity in crystal chemistry and lattice parameters among the various garnets (yttrium iron garnet, bismuth iron garnet, etc.) is utilized to create artificially layered heterostructures and superlattices. Rare earth (especially Eu) substitu...

Magnetic properties of amorphous Ni60Ag40 films

Amorphous Ni–Ag films were obtained on liquid nitrogen cooled Si substrates using DC magnetron sputtering. A series of magnetic and magneto-transport property measurements confirm that the film with Ni to Ag atomic ratio of 60:40 is an alloy of the two elements immiscible in equilibrium, with atomic-level intermixing. The magnetic properties of the new alloy are discussed in comparison with tho...
