Equiatomic FeRh films exhibit a unique metamagnetic phase transition. Thin film properties, crucial for spintronic devices, are influenced by substrate interfaces and strain, altering transition temperatures.

Area of Science:

  • Materials Science
  • Condensed Matter Physics
  • Nanotechnology

Background:

  • Equiatomic FeRh displays a first-order metamagnetic phase transition from antiferromagnetic to ferromagnetic states above room temperature (~370 K).
  • This transition is promising for multifunctional magnetic and spintronic devices, utilizing thermal and magnetic field energy for state changes.
  • Understanding and controlling FeRh properties in the extreme thin film limit (below 10 nm) is critical due to the significant role of interfaces.

Purpose of the Study:

  • To investigate the properties of FeRh thin films in the 2.5-10 nm thickness range grown on MgO substrates.
  • To understand the influence of strain and interfaces on the metamagnetic phase transition in thin film FeRh.
  • To correlate experimental observations with theoretical modeling to elucidate the role of atomic layers near the interface.

Main Methods:

  • Thin film growth of equiatomic FeRh on MgO substrates.
  • Magnetometry and structural measurements to characterize film properties.
  • Spin dynamics modeling to support experimental findings.

Main Results:

  • Perpendicular strain fields were observed in FeRh thin films grown on MgO.
  • The phase transition temperature of FeRh increases as the film thickness decreases.
  • Experimental results were corroborated by spin dynamics modeling, highlighting the interface's importance.

Conclusions:

  • The properties of thin film FeRh are significantly influenced by strain induced by the MgO substrate.
  • Interface effects, particularly the atomic layers closest to the substrate, play a critical role in the magnetic phase transition.
  • These findings are essential for the development of advanced spintronic devices utilizing FeRh thin films.
