Ferromagnetism01:31

Ferromagnetism

3.4K
Materials like iron, nickel, and cobalt consist of magnetic domains, within which the magnetic dipoles are arranged parallel to each other. The magnetic dipoles are rigidly aligned in the same direction within a domain by quantum mechanical coupling among the atoms. This coupling is so strong that even thermal agitation at room temperature cannot break it. The result is that each domain has a net dipole moment. However, some materials have weaker coupling, and are ferromagnetic at lower...

Paramagnetism01:30

Paramagnetism

3.1K
Paramagnets are materials with unpaired electrons that possess a finite magnetic moment. In the absence of a magnetic field, these moments are randomly oriented, and thus the net moment is zero. Under an external field, a torque acting on the moments tends to align them along the field's direction. However, the random thermal motion of electrons produces a torque opposite to the external field and tries to disorient the moments. These two competing effects align only a few moments along the...

Magnetic Susceptibility and Permeability01:31

Magnetic Susceptibility and Permeability

2.6K
In linear magnetic materials, like paramagnets and diamagnets, magnetization is proportional to the magnetic field intensity. The constant of proportionality, a dimensionless number, is called magnetic susceptibility. The value of the susceptibility depends on the type of material.
When diamagnetic materials are placed under an external magnetic field, the moments opposite to the field are induced. Hence, the susceptibility for diamagnets has a minimal negative value of 10-5–10-6. Since...

Diamagnetism

3.2K
Materials consisting of paired electrons have zero net magnetic moments. However, when these materials are placed under an external magnetic field, the moments opposite to the field are induced. Such materials are called diamagnets. Diamagnetism is the response of the diamagnets when placed in an external magnetic field.
Diamagnetism was discovered by Anton Brugmans in 1778 when he observed that bismuth gets repelled by magnetic fields, thus theorizing that diamagnets get repelled by magnets....

Magnetostatic Boundary Conditions01:28

Magnetostatic Boundary Conditions

1.7K
An electric field suffers a discontinuity at a surface charge. Similarly, a magnetic field is discontinuous at a surface current. The perpendicular component of a magnetic field is continuous across the interface of two magnetic mediums. In contrast, its parallel component, perpendicular to the current, is discontinuous by the amount equal to the product of the vacuum permeability and the surface current. Like the scalar potential in electrostatics, the vector potential is also continuous...

Colors and Magnetism

Color in Coordination Complexes
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...

Summary

High-order anisotropic magnetoresistance (AMR) was observed up to the 18th harmonic in iron films, challenging previous understanding. These findings reveal intrinsic, tunable higher-order AMR terms in cubic ferromagnets, opening new spintronic possibilities.

Area of Science:

  • Condensed matter physics
  • Materials science
  • Spintronics

Background:

  • Anisotropic magnetoresistance (AMR) describes resistance changes with magnetization direction.
  • Traditionally, only 2-fold and 4-fold AMR terms were considered symmetry-allowed in cubic materials.

Purpose of the Study:

  • To investigate high-order AMR harmonics beyond the established 2-fold and 4-fold terms.
  • To determine the symmetry, tunability, and microscopic origin of observed high-order AMR.

Main Methods:

  • Experimental observation of AMR up to the 18th harmonic in Fe(001) thin films.
  • Utilized angle-resolved transport measurements and Fourier analysis.
  • Theoretical analysis based on crystal symmetry, Fermi velocity, and relaxation time.

Main Results:

  • Observed high-order AMR harmonics (6-fold and higher) in cubic Fe(001) films.
  • Demonstrated that these high-order terms are intrinsic and tunable with temperature and film thickness.
  • Identified the microscopic origins: interplay of anisotropic Fermi velocity and scattering regimes.

Conclusions:

  • High-order AMR is an intrinsic, symmetry-allowed property of cubic ferromagnets.
  • Challenges the existing paradigm of AMR symmetry.
  • Provides benchmarks for spin-orbit transport theory and enables novel spintronic devices.
