Magneto-transport in a cryostat

Magneto-transport measurements in a cryostat system involve studying a material's electrical properties under extreme cold conditions. By subjecting the material to strong magnetic fields at near absolute zero temperatures, researchers can reveal how its electrical conductivity changes in response to magnetic influences. This method is crucial for understanding and developing novel materials with applications in electronics, superconductivity, and quantum technology.

Anomalous Hall effect

The anomalous Hall effect is a fascinating phenomenon in condensed matter physics. It involves the appearance of a transverse voltage in a conductor subjected to an external magnetic field, even when there's no net charge flow. This intriguing effect, observed in various materials, originates from the interaction between electron spin and their motion, making it a vital concept in spintronics and magnetic materials research.

Noncollinear antiferromagnets

Noncollinear antiferromagnets are magnetic materials with complex, non-uniform spin arrangements. Unlike conventional antiferromagnets where opposing spins align, in noncollinear antiferromagnets, neighboring spins adopt varied orientations. This unique behavior results in intriguing properties, including exotic magnetic phases, topological effects, and potential applications in future spintronic devices and information storage technologies.

Optical lithography

Optical lithography is a fundamental process in semiconductor manufacturing. It involves using light to project intricate patterns onto a photosensitive material, often a silicon wafer, to define the features of microelectronic circuits. This technique enables the production of smaller, faster, and more powerful integrated circuits, driving the advancements in modern electronics.The image on the left shows the result of exposure of a mask with impurities which are imprinted as the tiny bubbles next to the squares.

Surface Acoustic Waves

Surface acoustic waves (SAWs) are mechanical vibrations that travel along the surface of a solid material. Generated by interdigitated transducers, SAWs are crucial in diverse applications, including sensors, filters, and signal processing. Their ability to convey information while staying confined to the surface makes SAWs valuable for precise measurements and wireless communication systems.

Interdigitated transducers.

Interdigitated transducers (IDTs) are key components in generating surface acoustic waves (SAWs). Comprising interwoven finger-like electrodes, IDTs, when stimulated with an electrical signal, produce high-frequency SAWs on the surface of piezoelectric substrates. This technology is fundamental in various applications, from sensors to communication devices, harnessing the unique properties of SAWs for precise and efficient signal transmission and sensing.
