## Description
- description: A strain-induced phase transition is one of the noteworthy fields in
materials science and condensed matter physics. Electrical and optical switching
via strain-induced phase transitions at room temperature is applicable to straintronics,
which is an emerging field focused on low energy operation in next-generation
computing and memory devices. While strain-induced structural and magnetic transitions
have been extensively investigated, real-space observations of these phase transitions
are still a considerable challenge. In this study, we demonstrated the Lorentz
transmission electron microscopy (L-TEM) on magnetic textures under uniaxial compressive
strain. Transition behaviors of magnetic stripes are studied through the observation
of a (Fe0.63Ni0.3Pd0.07)3P magnet with S4 symmetry. Our L-TEM observations, coupled
with in-situ nanoindentation techniques, demonstrated a switching of the wavevector
(q) of magnetic stripe domains when the strain aligns along stripes, while a direction
of q doesn’t change when the strain is applied perpendicular to the stripes. These
observation results agree with expected transitions by micromagnetic simulations.
Moreover, calculation results by finite element method supports that the concentration
of compressive stress triggers a switching of magnetic stripes. These experiments
and simulations open a possibility to control the strain-induced transitions of
magnetic states in electrical devices.
