Thermal Strain

1.0K
Thermal strain is a concept that arises when we consider how temperature changes affect structures. Unlike the conventional assumption that structures remain constant under load, real-world scenarios often involve temperature fluctuations that can significantly impact these structures. Consider a homogeneous rod with a uniform cross-section resting freely on a flat horizontal surface. If the rod's temperature increases, the rod elongates. This elongation is proportional to the temperature...

Area of Science:

  • Condensed Matter Physics
  • Materials Science
  • Nanotechnology

Background:

  • Skyrmions are promising for low-energy, high-density information storage.
  • Stabilizing the skyrmion lattice (SkX) phase above room temperature is critical for practical applications.
  • The topological Hall effect aids in identifying skyrmion systems at higher temperatures.

Purpose of the Study:

  • To investigate the effect of tensile strain on FeGe thin films.
  • To explore the potential for room-temperature skyrmion lattice phase stabilization.
  • To characterize magnetic properties and topological Hall effect in strained FeGe.

Main Methods:

  • Epitaxial growth of atomically ordered FeGe thin films on Ge(111) substrates.
  • Application of approximately 4% tensile strain.
  • Magnetic characterization, including Curie temperature determination.
  • Measurement of the topological Hall effect across a temperature range.

Main Results:

  • Tensile strain enhanced the Curie temperature of FeGe films to 350 K (from 278 K bulk).
  • A strong topological Hall effect was observed from 10 K to 330 K.
  • A significant increase in the topological Hall effect magnitude was noted at 330 K, near the Curie temperature.

Conclusions:

  • Strained FeGe films exhibit significantly improved magnetic properties.
  • The observed phenomena suggest the potential for a skyrmion lattice phase above room temperature in strained FeGe.
  • This work paves the way for developing next-generation data storage technologies.
