Summary
Researchers discovered spontaneous in-plane anomalous Hall effect (AHE) in SrRuO3 films. This effect is controllable via spin magnetization direction, offering new possibilities for spintronic devices.
Area of Science:
- Condensed Matter Physics
- Materials Science

Background:
- Anomalous Hall effect (AHE) typically studied for out-of-plane responses.
- In-plane AHE offers new degrees of freedom for engineering Hall responses.
- Off-diagonal coupling in AHE is constrained by system symmetry.
Purpose of the Study:
- To elucidate in-plane anomalous Hall effect (AHE) in ferromagnetic oxide SrRuO3.
- To investigate spontaneous AHE and its coupling to spin magnetization.
- To explore control of in-plane Hall responses via spin direction.
Main Methods:
- Fabrication of (111)-orientated ultrathin SrRuO3 films.
- Systematic measurements of Hall response under varying magnetic field angles.
- Characterization of spin magnetization and its influence on AHE.
Main Results:
- Observation of spontaneous in-plane AHE at zero field in SrRuO3 films.
- Intrinsic coupling between in-plane AHE and in-plane spin magnetization.
- Complex Hall responses influenced by higher-order terms due to trigonal distortion.
Conclusions:
- Demonstrated versatile and controllable in-plane Hall responses in SrRuO3.
- Highlighted the role of out-of-plane orbital ferromagnetism in observed effects.
- Opened new avenues for engineering Hall responses in spintronic applications.

3.0K
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...

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.

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....

1.6K
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,...

01:31Magnetic Susceptibility and Permeability
2.3K
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...

Coordination compounds and complexes exhibit different colors, geometries, and magnetic behavior, depending on the metal atom/ion and ligands from which they are composed. In an attempt to explain the bonding and structure of coordination complexes, Linus Pauling proposed the valence bond theory, or VBT, using the concepts of hybridization and the overlapping of the atomic orbitals. According to VBT, the central metal atom or ion (Lewis acid) hybridizes to provide empty orbitals of suitable...
