Thermal stability of coupled ferromagnetic and superparamagnetic particles
, 2002 We consider a single-domain ferromagnetic particle with uniaxial anisotropy coupled to a single-domain soft ferromagnetic particle (superparamagnetic particle).

Quantum interference oscillations of the superparamagnetic blocking in an Fe8 molecular nanomagnet [PDF]
, 2013 We show that the dynamic magnetic susceptibility and the superparamagnetic blocking temperature of an Fe8 single molecule magnet oscillate as a function of the magnetic field Hx applied along its hard magnetic axis. These oscillations are associated with

Magnetic Viscosity Effect on Grounded-Wire TEM Responses and Its Physical Mechanism
IEEE Access, 2020 Magnetic viscosity (MV) effect is a disturbance to the transient electromagnetic method (TEM). This effect will cause slow decay at the intermediate-late time of the TEM responses, leading to erroneous interpretation.

Magnetic needles and superparamagnetic cells [PDF]
Physics in Medicine and Biology, 2007 Superparamagnetic nanoparticles can be attached in great numbers to pathogenic cells using specific antibodies so that the magnetically-labeled cells themselves become superparamagnets. The cells can then be manipulated and drawn out of biological fluids, as in a biopsy, very selectively using a magnetic needle. We examine the origins and uncertainties

Direct evidence for ferromagnetic spin polarization in gold nanoparticles [PDF]
, 2004 We report the first direct observation of ferromagnetic spin polarization of Au nanoparticles with a mean diameter of 1.9 nm using X-ray magnetic circular dichroism (XMCD). Owing to the element selectivity of XMCD, only the gold magnetization is explored.
