Ferromagnetism01:31

Ferromagnetism

2.9K
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

2.9K
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

2.2K
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...

Magnetostatic Boundary Conditions01:28

Magnetostatic Boundary Conditions

1.6K
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...

Magnetic Force Between Two Parallel Currents01:13

Magnetic Force Between Two Parallel Currents

4.5K
Two long, straight, and parallel current-carrying conductors exert a force of equal magnitude on one another. The direction of the force depends on the current direction in the conductors.
The force exerted by the magnetic field due to the first conductor over a finite length of the second conductor is given as the product of the current in the second conductor and  the vector product of the length vector along the current element and the field due to the first conductor. According to the...

Magnetic Fields01:27

Magnetic Fields

7.1K
A moving charge or a current creates a magnetic field in the surrounding space, in addition to its electric field. The magnetic field exerts a force on any other moving charge or current that is present in the field. Like an electric field, the magnetic field is also a vector field. At any position, the direction of the magnetic field is defined as the direction in which the north pole of a compass needle points.
A magnetic field is defined by the force that a charged particle experiences...

Area of Science:

  • Condensed Matter Physics
  • Materials Science
  • Quantum Technologies

Background:

  • Antiferromagnetic (AFM) materials offer a route to couple altermagnetic (AM) spin-splitting with the magneto-optical Kerr effect (MOKE).
  • AFM multiferroic bilayers present a platform for exploring novel electronic, magnetic, and optical phenomena.

Purpose of the Study:

  • To investigate the impact of interlayer sliding in AFM multiferroic bilayers on their properties.
  • To understand the dimension-driven AM crossover and the role of symmetry in spin-splitting.
  • To explore the control of electronic, magnetic, and magneto-optical properties via sliding ferroelectricity and Néel vector switching.

Main Methods:

  • First-principles calculations.
  • Symmetry analysis.
  • k·p modeling.

Main Results:

  • A dimension-driven AM crossover is observed: 2D paraelectric bilayers have spin-degenerate bands, while 3D counterparts show AM spin-splitting.
  • Interlayer sliding induces a ferroelectric state with compensated ferrimagnetism, leading to nonrelativistic spin-splitting.
  • Spin-orbit coupling in the ferroelectric phase generates alternating spin-polarized bands via Zeeman and Rashba effects.
  • Spin polarization, ferrovalley polarization, and Kerr angle are reversible by switching ferroelectricity or the Néel vector.

Conclusions:

  • Interlayer sliding in AFM multiferroic bilayers provides a mechanism to control coupled electronic, magnetic, and optical orders.
  • The findings highlight prospects for ultralow-power spintronic and optoelectronic devices leveraging these tunable properties.
