Ultrasensitive FMR Setup

A dedicated measurement setup for ferromagnetic resonance (FMR) studies is a low-cost solution ideal for laboratories working with magnetic materials and thin-films down to 1 nm in thickness. The our FMR setup features a compact design and can be integrated with existing laboratory infrastructure (electromagnet, power supply). The system is equipped with specialized software that automates measurements and streamlines data analysis. Thanks to its modular construction, the device can be quickly set up and tested on-site within a single day. It offers precise and repeatable measurements with minimal hardware requirements, providing an attractive alternative to more expensive solutions on the market.

Key Features & Capabilities:

• Broad Frequency Range: Operates across a wide range of microwave frequencies (typically 1-24 GHz, customizable) to probe various magnetic phenomena
• High Sensitivity: Optimized cavity design and low-noise electronics enable detection of FMR signals from ultra-thin films and small-volume samples.
• Versatile Sample Environment: Compatible with variable temperature cryostats, electromagnets for in-plane and out-of-plane field application, and options for angular-dependent measurements.
• Parameter Extraction: Coupled with our Advanced Analysis Software, the system facilitates extraction of key parameters such as:
  • Gilbert damping constant (α)
  • Effective magnetization (M_eff)
  • Magnetic anisotropy fields (uniaxial, cubic, etc.)
  • Exchange stiffness (A_ex)
  • g-factor
  • Inhomogeneous broadening
• Automated Measurements: Software control for automated frequency sweeps, field sweeps, and temperature ramps.
• Modular Design: Allows for customization and future upgrades to meet evolving research needs.

Applications:

• Characterization of novel spintronic materials.
• Development of magnetic memory (MRAM) and sensor devices.
• Investigation of spin dynamics in nanomagnets and magnonic crystals.
• Fundamental research in magnetism and condensed matter physics.

The Microspin Ultra-Sensitive FMR Setup is an indispensable tool for researchers pushing the frontiers of magnetism and spintronics. Contact us for detailed specifications, customization options, or to request a quote.
