Overview

Unlocking Spin‑Dependent Phenomena: The characterization of spintronic devices, magnetic random‑access memory (MRAM), and topological materials demands precise electrical measurements under controlled magnetic fields. At AIMRSE, we manufacture Magnetic Field Probe Stations that seamlessly integrate high‑field electromagnets or superconducting magnets with our precision probing platforms. Whether you are measuring Hall effect, anisotropic magnetoresistance (AMR), or tunneling magnetoresistance (TMR), our systems provide stable, uniform magnetic fields up to 9 T while maintaining the mechanical and electrical integrity required for sensitive device characterization.

System Architecture & Magnet Integration

Magnetic field probe station with electromagnet and micro-positioners Fig 1: AIMRSE magnetic field probe station configured for magneto‑transport and spintronic device characterization.

AIMRSE magnetic field probe stations are built around a rigid, non‑magnetic structure that minimizes field distortion and mechanical deflection under high magnetic forces. The sample stage is positioned precisely between the pole pieces of an electromagnet or within the bore of a superconducting magnet, with probe arms fabricated from high‑resistivity, non‑magnetic alloys such as titanium and phosphor bronze. Field strengths from 0.5 T to 9 T are available, with options for in‑plane, out‑of‑plane, or vector field rotation. Active field control and temperature integration (from 4 K to 400 K) enable comprehensive magneto‑transport studies. Our systems are deployed in leading research laboratories for MRAM bit characterization, Hall sensor calibration, spintronic material research, and topological insulator studies.

Available Magnetic Field Configurations

Electromagnet Systems (up to 2.5 T)

In‑Plane or Out‑of‑Plane Fields
Water‑cooled electromagnets with variable gap and field control via bipolar power supply. Ideal for Hall effect, magnetoresistance, and spin‑torque oscillator characterization at room and elevated temperatures.

Superconducting Magnet Systems (up to 9 T)

Cryogen‑Free or LHe‑Cooled
High‑field superconducting magnets integrated with cryogenic probe stations. Essential for quantum transport, fractional quantum Hall effect, and low‑temperature spintronics.

Vector Magnet Configurations

2‑Axis or 3‑Axis Field Control
Split‑pair or triple‑axis Helmholtz coils for arbitrary field orientation. Enables angular‑dependent magnetoresistance and spin‑torque ferromagnetic resonance (ST‑FMR) studies.

Custom Pole Piece & Bore Adapters

Tailored Sample Space
Custom pole piece geometries for specific sample sizes and field uniformity requirements. Adapters for existing magnet systems to accept AIMRSE probe station mechanics.

Core Engineering Advantages

Non‑Magnetic Probing Mechanics

All probe arms, positioner bodies, and sample stage components are fabricated from non‑magnetic materials to prevent field distortion and ensure that the sample experiences the intended magnetic field vector. This is critical for quantitative magneto‑transport measurements.

Field Uniformity & Stability

Our magnet systems are shimmed for ±0.1% field uniformity over the sample area. Closed‑loop Hall probe feedback ensures field stability better than 10 ppm, enabling high‑precision Hall coefficient and magnetoresistance ratio extraction.

Thermal & Field Synchronization

Integrated temperature control and magnetic field sweeps are synchronized through our software interface. Perform automated R(T,B) measurements and generate full phase diagrams of material properties as functions of both temperature and magnetic field.

Magnetic Field Probing FAQ

What is the maximum magnetic field available?

AIMRSE offers electromagnets up to 2.5 T at room temperature and superconducting magnets up to 9 T for cryogenic applications. Custom configurations for higher fields or specific bore sizes are available upon request.

Can the field orientation be changed during measurement?

Yes. Vector magnet configurations with two or three orthogonal coils allow electronic rotation of the field vector without mechanical sample movement. This is ideal for anisotropic magnetoresistance and spin‑torque measurements.

Are the probes affected by the magnetic field?

All probe arms, positioners, and sample mounts are constructed from non‑magnetic, high‑resistivity materials such as titanium, beryllium copper, and phosphor bronze. This prevents Lorentz force deflection and ensures that the probes do not perturb the field at the sample location.

Can I combine magnetic field with temperature control?

Yes. Our magnetic field probe stations are fully compatible with thermal chucks (‑65°C to 300°C) for electromagnets and cryogenic stages (4 K to 400 K) for superconducting magnets. Synchronized control enables automated magneto‑transport mapping.

Do you integrate with existing magnet systems in my lab?

Absolutely. We can design custom mounting flanges and probe arms to fit within the bore or pole gap of your existing electromagnet or superconducting magnet, saving capital while upgrading your measurement capabilities.
