DESCRIPTION:Speakers: Michael Farle (University of Duisburg-Essen\, German
 y\, and Immanuel Kant Baltic Federal University\, Russia)\nImagine a futur
 e in which food is used to activate specific immune reactions in a human b
 ody based on an external noninvasive magnetic stimulus. Dream of a materia
 l that stores and releases energy reversibly by temperature changes betwee
 n day and night. These visions may be realized by using magnetic nanoparti
 cles that are functionalized to be biocompatible\, environmentally stable 
 and recyclable\, self-healing\, and low-cost. \nIn this presentation I wil
 l discuss the basic concepts of magnetic nanomaterials and their magnetic 
 properties with a focus on how to tune specific parameters in a controlled
  fashion to achieve the dreams of the future. I will highlight state-of-th
 e-art experimental technologies that allow us to understand microscopic pr
 operties and interactions in relation to electronic structure changes caus
 ed by changes in size\, shape\, and composition of nanomaterials. Then I w
 ill discuss how this understanding is used when nanomagnets are functional
 ized for targeted drug delivery or composed to form macroscopic materials 
 for new energetic applications like magnetic refrigeration. I will demonst
 rate that the seemingly complex behavior of hybrid metal/metal\, metal/oxi
 de\, or oxide/oxide interface materials can be understood from the three f
 undamental interactions in magnetism: magnetic exchange interaction due to
  orbital overlap\, spin-orbit interaction due to inner- and intra-atomic r
 elativistic corrections (e.g.\, crystal field effects) and the long-range 
 magnetic dipolar interaction. Several examples will be presented\, includi
 ng the formation of above-room-temperature ferromagnetic interface layers 
 between low-temperature antiferromagnetic layers and the evolution of latt
 ices of magnetic textures (skyrmions) in confined dimensions. The talk wil
 l end with an episode in the life of an imaginary golf-playing couple in t
 he year 2040 who use their “Smart Magnet” (SMAG) phone to energize and
  heal their bodies on the green.\n\nhttps://indico.ific.uv.es/event/2851/c
