Influence of the magnetic nanoparticle coating on the magnetic relaxation time

open access: yesBeilstein Journal of Nanotechnology, 2020
Colloidal systems consisting of monodomain superparamagnetic nanoparticles have been used in biomedical applications, such as the hyperthermia treatment for cancer. In this type of colloid, called a nanofluid, the nanoparticles tend to agglomeration.

Magnetic order and disorder environments in superantiferromagnetic $$\hbox {NdCu}_{\mathbf{2}}$$ NdCu 2 nanoparticles

open access: yesScientific Reports, 2022
Magnetic nanoparticles exhibit two different local symmetry environments, one ascribed to the core and one corresponding to the nanoparticle surface. This implies the existence of a dual spin dynamics, leading to the presence of two different magnetic ...
