DESCRIPTION:Magnetic nanoparticles have been building blocks in application
 s ranging from high density recording to spintronics and nanomedicine. Mag
 netic anisotropies in nanoparticles arising from surfaces\, shapes and int
 erfaces in hybrid structures are important in determining the functional r
 esponse in various applications. In this talk I will first introduce the b
 asic aspects of anisotropy\, how to tune it in nanostructures and ways to 
 measure it. I will discuss resonant RF transverse susceptibility\, that we
  have used extensively\, as a powerful method to probe the effective aniso
 tropy in magnetic materials. Tuning anisotropy has a direct impact on the 
 performance of functional magnetic nanoparticles in biomedical application
 s such as contrast enhancement in MRI and magnetic hyperthermia cancer the
 rapy. There is a need to improve the specific absorption rate (SAR) or hea
 ting efficiency of nanoparticles for hyperthermia and I will focus on the 
 role of tuning surface and interfacial anisotropy with a goal to enhance S
 AR. Strategies going beyond simple spherical structures such as exchange c
 oupled core-shell nanoparticles\, nanowire\, nanotube geometries can be ex
 ploited to increase saturation magnetization\, effective anisotropy and he
 ating efficiency in magnetic hyperthermia. This lecture will combine insig
 hts into fundamental physics of magnetic nanostructures along with recent 
 research advances in their application in nanomedicine.\n\nCo-sponsored by
