A storage medium that stores commands, the commands being configured to enable at least one processor of an electronic device to perform at least one operation when executed by the at least one processor is provided. The at least one operation comprises identifying a remaining amount of a battery of the electronic device and a power consumption rate of the electronic device, and controlling, based on the remaining amount of battery and the power consumption rate, a driving circuit of the electronic device to switch a display of the electronic device from a first state to a second state, wherein a first area of the display is exposed in the first state, the first area including a second area and a third area and wherein the second area is exposed and the third area is not exposed in the second state.

Electronic device including extendable display for expanding and reducing display area that is visible from front side of housing and control method therefor

A signal transferring device includes a first structure that includes a first magnetic thin film structure having a first magnetic vortex configured to receive a signal as an input signal, a second structure that is spaced apart from at least one side of the first structure, the second structure including a second magnetic thin film structure having a second magnetic vortex configured to transfer the signal, and a third structure that is spaced apart from at least one side of the second structure, the third structure including a third magnetic thin film structure having a third magnetic vortex configured to output the signal from the signal transferring device. The first and third structures have a symmetrical shape and the second structure has an asymmetrical shape.

Signal transferring device and multiplexer using magnetic thin film structures

A core magnetization reversal method includes transforming the first magnetic skyrmion into a skyrmionium by applying a first alternating current (AC) magnetic field to the first magnetic skyrmion, and then transforming the skyrmionium into a second magnetic skyrmion by applying a second AC magnetic field to the skyrmionium. The first magnetic skyrmion may be formed on a hemispherical shell, which may be formed by (i) preparing a membrane having a plurality of protrusions, and (ii) stacking, on the membrane, a first layer including at least one of platinum (Pt), nickel (Ni), and palladium (Pd), and a second layer including a ferromagnetic material. The first and second AC magnetic fields may have different frequencies.
