 te specific immune reactions in a human body based on an external noninvas
 ive magnetic stimulus. Dream of a material that stores and releases energy
  reversibly by temperature changes between day and night. These visions ma
 y be realized by using magnetic nanoparticles that are functionalized to b
 e biocompatible\, environmentally stable and recyclable\, self-healing\, a
 nd low-cost.  In this presentation I will discuss the basic concepts of ma
 gnetic 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-the-art experimental technologies th
 at allow us to understand microscopic properties and interactions in relat
 ion to electronic structure changes caused by changes in size\, shape\, an
 d composition of nanomaterials. Then I will discuss how this understanding
  is used when nanomagnets are functionalized for targeted drug delivery or
  composed to form macroscopic materials for new energetic applications lik
 e magnetic refrigeration. I will demonstrate that the seemingly complex be
 havior of hybrid metal/metal\, metal/oxide\, or oxide/oxide interface mate
 rials can be understood from the three fundamental interactions in magneti
 sm: magnetic exchange interaction due to orbital overlap\, spin-orbit inte
 raction due to inner- and intra-atomic relativistic corrections (e.g.\, cr
 ystal field effects) and the long-range magnetic dipolar interaction. Seve
 ral examples will be presented\, including the formation of above-room-tem
 perature ferromagnetic interface layers between low-temperature antiferrom
 agnetic layers and the evolution of lattices of magnetic textures (skyrmio
 ns) in confined dimensions. The talk will end with an episode in the life 
 of an imaginary golf-playing couple in the year 2040 who use their “Smar
 t Magnet” (SMAG) phone to energize and heal their bodies on the green.
