MICROWAVE ABSORPTION (MMMA) - A CONTACLESS METHOD TO STUDY SUPERCONDUCTORS AND MAGNETIC NANOSTRUCTURES
Journal Title: Metrology and Measurement Systems - Year 2006, Vol 13, Issue 2
Abstract
Magnetically Modulated Microwave Absorption (MMMA) is a sensitive differential method to study magnetoresistence related to the voltage fluctuation in nonhomogeneous superconducting systems with Josephson junctions (JS) and in magnetic systems exhibiting giant magnetoresistence (GMR). The MMMA method has been successfully established after the discovery of polycrystalline high temperature superconductors with high concentration of Josephson junctions. MMMA proved to be the third method besides resistivity and magnetic susceptibility measurements to determine critical temperature Tc. In magnetic nanostructures MMMA enables to determine GMR(H) and magnetization reversal.
