The field of spintronics, which integrates the charge and spin properties of electrons to develop electronic devices with enhanced functionality and energy efficiency, has expanded into new applications.

Beyond current technologies such as hard disk drive read heads and magnetic random-access memory (MRAM), researchers are now investigating flexible spintronics for use in wearable devices and sheet-type sensors.

For these applications, detecting small changes in mechanical stress through electrical resistance modulation is essential. This requires not only materials with significant magnetoresistance effects but also control over their magnetoelastic properties.
