Scientists discover new material for gen-next data storage devices

Scientists have developed a new material - the first ever magnetic photoconductor - that may lead to next generation of memory-storage systems, featuring higher capacities with low energy demands.
●    Scientists at Ecole Polytechnique Federale de Lausanne in Switzerland have now developed ferromagnetic photovoltaic material whose magnetic order can be rapidly changed without disrupting it due to heating.
●    Perovskite photovoltaics are gradually becoming a cheaper alternative to current silicon systems, drawing much interest from energy scientists.
●    Magnetism in material arises from the interactions of localised and moving electrons of the material; in a way, it is the result of competition between different movements of electrons.
●    This means that the resulting magnetic state is wired in the material and it cannot be reversed without changing the structure of electrons in the material's chemistry or crystal structure.
●    This new crystal structure combines the advantages of both ferromagnets, whose magnetic moments are aligned in a well-defined order, and photoconductors, where light illumination generates high density free conduction electrons.
