Magnetic properties of CoO nanoparticles [PDF]
The European Physical Journal D, 1999 The magnetic circular X-ray dichroism of CoO nanoparticles was measured at low temperatures and in high magnetic fields. The particles show a superparamagnetic behaviour at room temperature, and a large orbital contribution to the magnetic moment at low temperatures was observed.

Effect of large mechanical stress on the magnetic properties of embedded Fe nanoparticles
Beilstein Journal of Nanotechnology, 2011 Magnetic nanoparticles are promising candidates for next generation high density magnetic data storage devices. Data storage requires precise control of the magnetic properties of materials, in which the magnetic anisotropy plays a dominant role.

Preliminary report on MFM measurements on magnetic nanofiber mats
Communications in Development and Assembling of Textile Products, 2021 Nanofiber mats can be produced unambiguously by electrospinning. Besides pure polymers or polymer blends, such nanofibers can also contain metals, ceramics, etc., often introduced in the form of nanoparticles embedded in the spinning solution. Especially

Positive and negative magnetocapacitance in magnetic nanoparticle systems
, 2006 The dielectric properties of MnFe$_2$O$_4$ and $\gamma$-Fe$_2$O$_3$ magnetic nanoparticles embedded in insulating matrices were investigated. The samples showed frequency dependent dielectric anomalies coincident with the magnetic blocking temperature ...

Magnetic Properties of Bacterial Nanoparticles
Acta Physica Polonica A, 2009 The objective of this study is to prepare and study magnetic properties of biological magnetic nanoparticles (magnetosomes) as a product of biomineralization process of magnetotactic bacteria Magnetospirillum sp. AMB-1. From temperature dependence of remanent magnetization and coercive field the Verwey transition is clearly seen at 105 K as a ...
