Critical Phenomena in Magnetic Nanowires

Journal of Nanoscience and Nanotechnology, 2009
In this paper we report the first experimental study of critical phenomena in case of magnetic nanowires of nickel near the ferromagnetic-paramagnetic transition from the electrical transport properties. Nickel nanowire arrays, prepared by potentiostatic electrodeposition of nickel inside pores of nanoporous anodic alumina template were well ...

Magnetism from conductors and enhanced nonlinear phenomena

, 1999
We show that microstructures built from nonmagnetic conducting sheets exhibit an effective magnetic permeability /spl mu//sub eff/, which can be tuned to values not accessible in naturally occurring materials, including large imaginary components of /spl

Superconducting phenomena in systems with unconventional magnets

Journal of Physics: Condensed Matter
In this work we review the recent advances on superconducting phenomena in junctions formed by superconductors and unconventional magnets (UM). Conventional magnets, such as ferromagnets and antiferromagnets, are characterized by broken time-reversal ...

Electric and Magnetic Phenomena

2021
This chapter treats the responses of bulk matter to constant external electric and magnetic fields. The concepts of electric and magnetic dipole moments are reviewed, modifications to thermodynamics needed to accommodate field effects, and the statistical mechanical descriptions of polarizable media in the presence of applied fields are developed.

Critical magnetic phenomena

Physics Bulletin, 1978
A variety of crystals with magnetic properties approximating to those of 'ideal' one (Id) and two (2d) dimensional arrays of localised spins, much studied by theoreticians, are now available for experimental study. Many of the ideal systems exhibit no long-range magnetic order at low temperatures, so that short-range effects become important giving ...

Magnetic phenomena in UNi1−Rh Al compounds

Journal of Alloys and Compounds, 1999
Abstract We report on structure investigation and magnetization study of UNi 1− x Rh x Al solid solutions between an antiferromagnet UNiAl and a ferromagnet URhAl. The ZrNiAl-type hexagonal crystal structure of the parent compounds is preserved in the whole concentration range.

Magnetic phenomena

2004
In this chapter we deal with a number of magnetic properties and their directional dependence: pyromagnetism, magnetic susceptibility, magnetoelectricity, and piezomagnetism. In the course of dealing with these properties, two new ideas are introduced: magnetic symmetry and axial tensors.
