In this paper, we discuss several strategies to tailor magnetic properties related to the magnetic anisotropy energy, such as the blocking temperature or the low temperature coercivity, of magnetic nanoparticles or materials made with magnetic nanoparticles. We describe a first approach that consists in synthesizing and dispersing bi and tri-magnetic core-shell nanoparticles that include a core made of a material with a weak anisotropy energy density and a shell made with a material with a large anisotropy energy density. This approach is a promising route to tune the blocking temperature of low temperature coercivity of a particle without altering its magnetization and with a good control of its size. Additionally, we also explore another route for the control of the shape of the hysteresis loop of material made with magnetic nanoparticles that consists in the simple mixture of magnetically soft and hard magnetic nanoparticles to create binary mixtures. In this case, it is the mixing ratio that allows one to adjust the properties of the final material.
