Magnetostatic Boundary Conditions01:28

Magnetostatic Boundary Conditions

1.5K
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 Fields

7.0K
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...

Magnetic Field due to Moving Charges

11.3K
A stationary charge creates and interacts with the electric field, while a moving charge creates a magnetic field.
Consider a point charge moving with a constant velocity. Like the electric field, the magnetic field at any point is directly proportional to the magnitude of the charge and inversely proportional to the square of the distance between the source point and the field point. However, unlike the electric field, the magnetic field is always perpendicular to the plane containing the line...

Potential Due to a Magnetized Object

Magnetic dipoles in magnetic materials are aligned when placed under an external magnetic field. For paramagnets and ferromagnets, dipole alignment occurs in the direction of the magnetic field. However, the dipoles align opposite to the field in the case of diamagnets. This state of magnetic polarization due to the external field is called magnetization. Magnetization is defined as the dipole moment per unit volume. It plays a similar role to polarization in electrostatics.

Diamagnetism01:26

Diamagnetism

2.9K
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....

Magnetic Force01:18

Magnetic Force

1.7K
In addition to the electric forces between electric charges, moving electric charges exert magnetic forces on each other. A magnetic field is created by a moving charge or a group of moving charges known as the electric current. A magnetic force is experienced by a second current or moving charge in response to this magnetic field. Fundamentally, interactions between moving electrons in the atoms of two bodies produce magnetic forces between them.
The magnetic force acting on a moving charge...

Area of Science:

  • Condensed Matter Physics
  • Materials Science

Background:

  • Bubble skyrmions are topological magnetic quasiparticles with potential applications in spintronics.
  • Controlling skyrmion configurations, such as Bloch-like and Néel-like, is crucial for device functionality.
  • The Dzyaloshinskii-Moriya interaction is typically required to stabilize Néel-type skyrmions.

Purpose of the Study:

  • To investigate the interaction between two bubble skyrmions.
  • To analyze how the separation and relative positioning of skyrmions influence their magnetic parameters.
  • To explore methods for stabilizing Néel-type skyrmion configurations without relying on the Dzyaloshinskii-Moriya interaction.

Main Methods:

  • Detailed analytic and numerical analysis.
  • Micromagnetic calculations were performed to simulate skyrmion behavior.
  • Investigated skyrmion interactions in both in-plane and vertical configurations.

Main Results:

  • In-plane skyrmion separation showed weak variation in magnetic parameters.
  • Vertical skyrmion alignment exhibited strong variations in magnetic parameters with separation.
  • A transition from Bloch-like to Néel-like skyrmion configuration was observed with decreasing vertical separation due to magnetostatic interactions.

Conclusions:

  • Bubble skyrmion configurations can be controlled by their vertical separation.
  • Néel-type skyrmion stabilization is achievable via magnetostatic interactions, independent of the Dzyaloshinskii-Moriya interaction.
  • These findings offer a pathway for controlling skyrmion parameters in magnetic spintronic devices.
