In a study published in Nature Communications, Prof. Xiang Bin's group from University of Science and Technology of China of the Chinese Academy of Sciences, in collaboration with Assoc. Prof. Wang Zhi from Sun Yat-sen University, discovered the long-range skin Josephson supercurrent across a van der Waals ferromagnet.

By intercalating protons into van der Waals ferromagnet Cr1.2Te2 nanoflakes, a group of researchers successfully induced a room-temperature magnetic phase transition from ferromagnetism to antiferromagnetism.

Physicists at MIT have directly stimulated atoms in an antiferromagnetic material using a terahertz laser, a light source that oscillates more than a trillion times per second.

Holding the right material at the right angle, researchers have discovered a strategy to switch the magnetization in thin layers of a ferromagnet -- a technique that could eventually lead to the development of more energy-efficient magnetic memory devices.

A common metal paper clip will stick to a magnet. Scientists classify such iron-containing materials as ferromagnets. A little over a century ago, physicists Albert Einstein and Wander de Haas reported a surprising effect with a ferromagnet. If you suspend an iron cylinder from a wire and expose it to a magnetic field, it will start rotating if you simply reverse the direction of the magnetic field.

Antiferromagnets have zero net magnetization and are insensitive to external magnetic field perturbations. Antiferromagnetic spintronic devices hold great promise for creating future ultra-fast and energy-efficient information storage, processing, and transmission platforms, potentially leading to faster and more energy-efficient computers.

Society's increasing use of electronic devices motivates the search for new and better data storage techniques. Magnetic storage devices, such as hard disk drives, have been the mainstays for data storage over the past few decades. However, these devices, which use ferromagnetic bit orientation to store data, are fast approaching their physical limits. Replacing ferromagnets with antiferromagnets, the magnetic…

Microelectronics forms the foundation of much modern technology today, including smartphones, laptops and even supercomputers. It is based on the ability to allow and stop the flow of electrons through a material. Spin electronics, or spintronics, is a spinoff. It is based on the spin of electrons, and the fact that the electron spin along with the electric charge creates a magnetic field.

A Monash University-led research team has discovered that a structure comprising an ultra-thin topological insulator sandwiched between two 2D ferromagnetic insulators becomes a large-bandgap quantum anomalous Hall insulator. Such a heterostructure provides an avenue towards viable ultra-low energy future electronics, or even topological photovoltaics. Topological insulator: the filling in the sandwich In the…

Researchers at Tohoku University and Massachusetts Institute of Technology (MIT) have unveiled a representative effect of the anomalous dynamics at play when an electric current is applied to a new class of magnetic materials called non-collinear antiferromagnets. Their findings were published in the journal Nature Materials on August 3, 2023.

The so-called superconducting (SC) diode effect has recently attracted significant attention within the physics research community, due to its potential value for developing new technologies. This effect provides a key example of nonreciprocal superconductivity, as materials hosting it are essentially superconducting in one current flow direction and resistive in the other.

Electronics play a pivotal role in today's information society. Yet only the electron charge in electronic devices is at play, making energy dissipation an increasingly pressing issue that thwarts further development. Spintronics, an interdisciplinary field in which an electron's charge and spin degrees of freedom are utilized simultaneously, enables electric control of magnetism and vice versa, paving a path…

A research team has discovered that sandwiching a topological insulator between two 2D ferromagnetic insulators provides a quantum avenue towards ultra-low energy future electronics, or topological photovoltaics.

Magnetic domains walls are known to be a source of electrical resistance due to the difficulty for transport electron spins to follow their magnetic texture. This phenomenon holds potential for utilization in spintronic devices, where the electrical resistance can vary based on the presence or absence of a domain wall.

Spintronics uses the spins of electrons to perform logic operations or store information. Ideally, spintronic devices could operate faster and more energy-efficiently than conventional semiconductor devices. However, it is still difficult to create and manipulate spin textures in materials.

They just needed a little light.

A research team led by a physicist at the University of California, Riverside, has demonstrated a new magnetized state in a monolayer of tungsten ditelluride, or WTe2, a new quantum material. Called a magnetized or ferromagnetic quantum spin Hall insulator, this material of one-atom thickness has an insulating interior but a conducting edge, which has important implications for controlling electron flow in…
