Magnetotribology of ferromagnetic/ferromagnetic sliding couple
Wear, 2007Abstract Applied magnetic field around the rotating sliding ferromagnetic steel/steel modifies the friction and the wear behaviour of the contact. The friction tests where conducted in ambient air or in high vacuum chamber 10 −5 Pa. The applied normal loads are 0.1, 18.5 and 37 N. Without magnetic field, the contact is ductile steel against steel in

Graphene-like two-dimensional materials have garnered tremendous interest as emerging device materials for nanoelectronics due to their remarkable properties. However, their applications in spintronics have been limited by the lack of intrinsic magnetism.

Superconductivity and Ferromagnetism
IBM Journal of Research and Development, 1962Superconductivity and ferromagnetism were considered exclusive phenomena for many decades. Ever since Kamerlingh Onnes' discovery that strong magnetic fields will destroy superconductivity it had been assumed that the large internal, or Weiss field, in a ferromagnet would never permit the occurrence of superconductivity.

Tunneling Magnetoresistance in Ferromagnet/Insulator/Ferromagnet Junctions
International Journal of Modern Physics B, 1997A δ-type potential with complex prefactor is modeled on the tunneling barrier of a thin insulator (I) film separating two ferromagnetic (FM) films. By matching value and slope of wave functions across the tunneling barrier of a FM/I/FM junction, we obtain a general expression for tunneling conductance as a function of relative orientation θ between ...

Physical Review B, 1998
The tunneling conductance (TC) and magnetoresistance (TMR) are investigated for magnetic junctions consisting of two ferromagnetic electrodes separated by a ferromagnetic insulator (semiconductor). The investigations are based on the nearly-free-electron approximation.

Ferromagnetism of UFe2 and Comparison with the Ferromagnetic Theories
Journal of Applied Physics, 1963The intermetallic compound UFe2 is ferromagnetic. A considerable number of magnetization isotherms have been obtained from 200°K down to 4.2°K with applied field up to 14 000 Oe. The Curie temperature has been determined to be 172°K and the Bohr magneton number 1.02 per UFe2 molecule.

Magnetoresistance in Ferromagnet/Semimetal/Ferromagnet Junctions
Japanese Journal of Applied Physics, 2004Electrical conductance and magnetoresistance (MR) in ferromagnet (FM) junctions with a nonmagnetic (NM) spacer are calculated within the ballistic limit for the current perpendicular to the junction planes. Emphasis is placed on the roles of the electronic states of the NM spacer in the MR. The MR shows a maximum when the electronic structure of the NM

A ferromagnetic resonance investigation of ferromagnetic coupling
Journal of Physics D: Applied Physics, 1997We present the ferromagnetic resonance (FMR) mode characteristics of two ferromagnetically coupled layers. Calculations are given for an applied DC magnetic field perpendicular to the film plane. The analysis predicts the number, positions, intensities and linewidths of the FMR peaks as functions of the coupling strength K.

Physical Review E, 2009
The self-propelling motion of the flexible ferromagnetic swimmer is described. Necessary symmetry breaking is achieved by the buckling instability at field inversion. The characteristics of self-propulsion are in good agreement with the numerical calculations of the Floquet multipliers for the ferromagnetic filament under the action of ac magnetic ...
