The Hall Effect

The Hall Effect

Edwin H. Hall, in the year 1879, devised an experiment that could be used to identify the polarity of the predominant charge carriers in a conducting material. From a historical perspective, this experiment was the first to demonstrate that the charge carriers in most metals are negative.

π Electron Effects on Chemical Shift: Overview

π Electron Effects on Chemical Shift: Overview

An applied magnetic field causes loosely bound π-electrons in organic molecules to circulate, producing a local or induced diamagnetic field over a large spatial volume. As the molecules tumble in solution, the field generated by π-electrons in spherical substituents results in a zero net field. However, the net field generated by π-electrons in non-spherical substituents is not zero. The effect of this induced field depends on the orientation of the molecule with respect to B0, resulting in...

Paramagnetism

Paramagnetism

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...

Diamagnetism

Diamagnetism

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.

Potential Due to a Magnetized Object

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.
The vector...

Atomic Nuclei: Nuclear Relaxation Processes

Atomic Nuclei: Nuclear Relaxation Processes

In the absence of an external magnetic field, nuclear spin states are degenerate and randomly oriented. When a magnetic field is applied, the spins begin to precess and orient themselves along (lower energy) or against (higher energy) the direction of the field. At equilibrium, a slight excess population of spins exists in the lower energy state. Because the direction of the magnetic field is fixed as the z-axis, the precessing magnetic moments are randomly oriented around the z-axis. This...

Background:

The quantum Hall effect (QHE) and quantum anomalous Hall effect (QAHE) traditionally require out-of-plane magnetic fields or magnetization.
Existing research primarily focuses on systems with out-of-plane magnetic properties.

Purpose of the Study:

To predict and theoretically investigate the induction of the quantum anomalous Hall effect (QAHE) using only in-plane magnetization.
To explore realistic material systems and general conditions for this novel phenomenon.

Main Methods:

Symmetry analysis to determine the general conditions for in-plane magnetization-induced QAHE.
Theoretical prediction for two specific material systems: magnetically doped Bi2Te3 thin films and strained HgMnTe quantum wells.

Main Results:

Demonstrated that in-plane magnetization, without any out-of-plane magnetic field, can induce the quantum anomalous Hall effect.
Identified Bi2Te3 thin films and HgMnTe quantum wells as potential platforms for observing this effect.

Conclusions:

The quantum anomalous Hall effect can be realized with in-plane magnetization, broadening the scope of materials research.
Proposed an experimental setup to verify the effect, potentially leading to new QAHE material discovery.
