V001 / JSI / T109


Researchers from the Jožef Stefan Institute (Department for Materials Synthesis and Department for Complex Matter) and the University of Ljubljana, Darja Lisjak, Alenka Mertelj and Martin Čopič, in collaboration with researchers from the USA (University in Boulder, Lawrence Berkeley National Laboratory and Case Western Reserve University) have discovered that suspensions of magnetic nanoplatelets in butanol exhibit ferromagnetic ordering. Its zero-field magnetization produces distinctive magnetic self-interaction effects, including liquid-crystal textures of fluid block domains arranged in closed flux loops, and makes this phase highly sensitive, with it dramatically changing shape even in the Earth’s magnetic field. The discovery was published in Nature Communications.
