Abstract Scope |
Magnetic properties are important in various materials with applications ranging from magnetic memory to structural alloys. In most cases, the magnetization measurements are done on bulk samples that is ‘bulk measurements’. However, knowing the mesoscopic distribution of properties could be crucial as they can be very different from bulk properties. Here, I will introduce our magnetic imaging technique utilizing superconducting nanoscale sensors. I will showcase several studies from our laboratory and other works. Examples of the studied mesoscale objects and effects include domains, crystalline grains, composite nanoparticles, magnetostriction, edge magnetization, magnetization at dislocations, magnetization change from interdiffusion etc. I will summarize my talk by outlining prospective studies of relation between magnetic and other properties for improving the overall material performance. |
