TLDR
In this paper, the authors performed magnetic susceptibility measurements on RuSr2Eu15Ce05Cu2O10−δ (Ru1222) material and found that the magnetization versus applied field loops do not saturate even at very high applied fields, resulting in the short range magnetic order in the system, which facilitates the formation of clusters that freeze at low temperature.Abstract:
Systematic dc and ac magnetic susceptibility measurements performed on RuSr2Eu15Ce05Cu2O10−δ (Ru1222) demonstrate a paramagnetic to ferromagnetic transition around 95 K The third harmonic of the ac susceptibility reveals that the system undergoes a spin glass transition below 75 K The features of the zero-field cooled and field cooled dc magnetization curves of Ru1222 material resemble those of a cluster glass state, rather than those of a canonical spin glass state The magnetization versus applied field loops do not saturate, even at very high applied fields, resulting in the short range magnetic order in the system, which facilitates the formation of clusters that freeze at low temperature The temperature dependence of the second and third harmonic ac susceptibilities further confirms the coexistence of a cluster glass state and ferromagnetic order in the Ru1222 systemread more

Magnetic Functionalized Nanoparticles for Biomedical, Drug Delivery and Imaging Applications
TL;DR: Metal nanoparticles possess properties that allow them to be directed around the body with a magnetic field or directed to a magnetic implant, which opens up the potential to conjugate various bio-cargos to the nanoparticles that could then be directed for treatment in the body.

Structure and microstructure of the ferromagnetic superconductor RuSr 2 GdCu 2 O 8
TL;DR: In this paper, the average crystal structure is tetragonal at both 10 and 295 K, but a superstructure resulting from coherent rotations of the RuO 6 octahedra within subdomains of 50--200 \AA{} are observed by electron diffraction.
