Simultaneous imaging of ferromagnetic and ferroelectric domains

Researchers have discovered a new way to simultaneously image both the ferromagnetic and the ferroelectric domain structures of multilayer devices in which a ferromagnetic film is grown on a ferroelectric substrate. These structures have attracted significant recent interest due to their ability to efficiently use voltage to change the magnetization in low-energy magnetic devices.

Creating nanostructures using simple stamps

Nanostructures of virtually any possible shape can now be made using a combination of techniques. Especially the unique properties of so-called perovskites can be exploited further: their crystal structure is not influenced by the process.

'Stealth' nanoparticles could improve cancer vaccines

Cancer vaccines have recently emerged as a promising approach for killing tumor cells before they spread. But so far, most clinical candidates haven't worked that well. Now, scientists have developed a new way to deliver vaccines that successfully stifled tumor growth when tested in laboratory mice. And the key is in the vaccine's unique stealthy nanoparticles.

All directions are not created equal for nanoscale heat sources

Thermal considerations are rapidly becoming one of the most serious design constraints in microelectronics, especially on submicron scale lengths. A new study has shown that standard thermal models will lead to the wrong answer in a three-dimensional heat-transfer problem if the dimensions of the heating element are on the order of one micron or smaller.

Novel approach to magnetic measurements atom-by-atom

Having the possibility to measure magnetic properties of materials at atomic precision is one of the important goals of today's experimental physics. Researchers propose a new method, utilizing properties of the quantum world - the phase of the electron beam - to detect magnetism with atom-by-atom precision.
