In the last decade, the information processing has been a focus of interest for its potential applications in many fields of the society. Nowadays, there are a lot of systems able to storage and process information in a fast way. However, the desire of apply the Internet of Things in all possible objects and places, requires the development of new processing technologies that work in nano and micro scale in an efficient and sustainable way. Regarding to this field, multifunctional oxides have attracted special attention for their capacity to modify their magnetic or electric properties by applying an adequate stimulus. In specific, superconducting cuprates mixed with ferromagnetic materials (FM-SC hybrids) have presented novel and unique magnetic tunability. Here, we show that by combining YBCO (SC) and permalloy (FM) materials in hybrid devices, one can manipulate magnetic textures, through loss-less superconducting stray fields or transport super-currents. Multiple magnetic states with different magnetoresistance signal can be stabilized at remanence, and modified by applying small magnetic fields or currents [1]. The proposed approach opens new venues for energy-efficient information storage and manipulation.
