Reversible hysteresis loop tuning
We utilize antiferromagnetically coupled bilayer structures to magnetically tune hysteresis loop properties. Key element of this approach is the non-overlapping switching fi eld distribution of the two magnetic layers that make up the system: a hard magnetic CoPtCrB layer (HL) and a soft magnetic CoCr layer (SL). Both layers are coupled antiferromagnetically through an only 0.6-nm-thick Ru inte...
متن کاملSpin and orbital magnetic moments of Fe3O4.
We present measurements of the spin and orbital magnetic moments of Fe3O4 by using SQUID and magnetic circular dichroism in soft x-ray absorption. The measurements show that Fe3O4 has a noninteger spin moment, in contrast to its predicted half-metallic feature. Fe3O4 also exhibits a large unquenched orbital moment. Calculations using the local density approximation including the Hubbard U metho...
متن کاملAmphiphilic and magnetic behavior of Fe3O4 nanocrystals.
Fe(3)O(4) (magnetite) nanocrystals with an average size of 13 nm were prepared using a specially synthesized polymeric stabilizer (poly-4-vinylpyridine-co-acrylamidoethylamine-co-polyethyleneglycol-co-polyethyleneglycolic acid) that bears reactive groups for further functionalization. The polymer shell made the nanocrystals amphiphilic, i.e. they are soluble in pentanol, water and dichlorometha...
متن کاملMagnetic hysteresis and domain structure
2014 A brief survey is made of some of the problems involved in the development of experimental methods of obtaining information on the domain processes involved in the low field magnetization of polycrystalline materials. LE JOURNAL DE PHYSIQUE ET LE RADIUM TOME 20, FÉVRIER 1959, This paper represents an attempt to summarise briefly some of the problems involved in the development of an unders...
متن کاملMagnetic Cation Distribution in Nanocrystalline Fe3O4 Spinel
Neutron diffraction study of nanostructured magnetite was performed at room temperature. The actual grain-size was determined from evaluation of X-ray diffraction profiles by the modified Williamson-Hall plot. The atomic structure parameters and the sublattice magnetic moments were determined using the Rietveld refinement of the neutron diffraction spectra. The sublattice magnetization at the o...
