University of Illinois Researchers Report Novel Technique to Manipulate Magnetization at Nanoscale

Researchers at the University of Illinois at Urbana-Champaign have reported physical mechanisms that use heat to manipulate magnetic information. Unlike the conventional methods that involve application of magnetic fields, these mechanisms are based on the transport of heat energy, providing a suitable way to control magnetization at nano-level.

Nanomagnet Islands Arranged to Create Shakti Artificial Spin Ice Configuration

Nanomagnet Islands Arranged to Create Shakti Artificial Spin Ice Configuration

For the first time, nanomagnet islands or arrays were arranged into an exotic structure (called “shakti”) that does not directly relate to any known natural material. The shakti artificial spin ice configuration was fabricated and reproduced experimentally. [More]
Liposomes, Magnetic Nanoparticles and Photosensitizers Combined to Fight Cancer

Liposomes, Magnetic Nanoparticles and Photosensitizers Combined to Fight Cancer

By combining, in a liposome, magnetic nanoparticles and photosensitizers that are simultaneously and remotely activated by external physical stimuli (a magnetic field and light), scientists at the Laboratoire Matière et Systèmes Complexes (CNRS/Université Paris Diderot) and the Laboratoire Physicochimie des Electrolytes et Nanosystèmes Interfaciaux (CNRS/UPMC), obtained total tumor regression in mice.

Magnetic Nanoparticles Open the Blood-Brain Barrier to Deliver Molecules to the Brain

Magnetic nanoparticles can open the blood-brain barrier and deliver molecules directly to the brain, say researchers from the University of Montreal, Polytechnique Montréal, and CHU Sainte-Justine. [More]
Theoretically, Direction of Spin of Nanoscale Magnets Can Be Controlled Remotely

Theoretically, Direction of Spin of Nanoscale Magnets Can Be Controlled Remotely

In the eyes of physicists, magnetic molecules can be considered as nanoscale magnets. Remotely controlling the direction in which they rotate, like spinning tops, may intuitively be difficult to achieve. However, Russian physicists have just demonstrated that it is theoretically possible to do so. They have shown that a change of direction in the circular polarisation of an external magnetic field leads to a change in the direction of the mechanical rotation of the molecule. [More]

Diamond Nanocrystal Helps Map Magnetic Field Around a Micro-Particle

Measuring faint magnetic fields is a trillion-dollar business. Gigabytes of data, stored and quickly retrieved from chips the size of a coin, are at the heart of consumer electronics. Even higher data densities can be achieved by enhancing magnetic detection sensitivity---perhaps down to nano-tesla levels. [More]

Scientists Develop Ultrathin Magnetic Sensor with Extraordinary Mechanical Robustness

Scientists from Germany and Japan have developed a new magnetic sensor, which is thin, robust and pliable enough to be smoothly adapted to human skin, even to the most flexible part of the human palm. This is feeding the vision to equip humans with magnetic sense. [More]
