Gels with magnetic properties

open access: yes, 2007
Materials producing strain in magnetic field are known as magnetoelastic or magneto strictive materials. A new type has been developed by preparing magnetic field sensitive gels, called ferrogels. Single domain, magnetic particles of colloidal size are incorporated into chemically cross-linked polyvinyl-alcohol hydrogels.

A quantitative study of magnetization transfer in MAGIC gels [PDF]

open access: yesPhysics in Medicine and Biology, 2003
Magnetization transfer (MT) has been measured quantitatively as a function of radiation dose in MAGIC polymer gels. The MT rates between the free and immobile macromolecular proton pools (kmr and kfm), and the ratio of the sizes of these coupled proton pools (Pm/Pf), were measured by analysing the response to an inversion recovery sequence. While pm/pf
