5201 Horizontal Projected Field
By “projecting” magnetic field outside the Model 5201 Electromagnet, a volume of approximately uniform magnetic flux density is made available for magnetic measurements on small samples. Open access to the sample surface is available for diagnostic probes and radiation from laser and synchrotron radiation sources.
The Bx component of the field is uniform to +/-1% in a planar, thin volume of 2 x 10 x 0.2mm (x, y, z) which is particularly appropriate for studies of in-plane effects in planar samples oriented parallel to the Electromagnet surface.
Bx can be computer or manually controlled over the range of +/-0.4T (4000G) at z = 2mm from the Electromagnet surface, decreasing to a range of +/-0.1T(1000G) at z = 12mm.
The Bz component of the field approaches a range of +/- 0.30T (3000G) as the distance X(mm), x=0 being an equidistant distance between the two poles, at +/-5mm. As the x distance approaches 0 the Bz component of the field also approaches 0.
Small size and low weight enable the 5201 to be mounted in any orientation on standard transverse and rotary motion stages for accurate control of the projected field in position and angle with respect to the sample. The 5201 projected field can be introduced into a vacuum chamber or cryostat via a reentrant tube of 100mm (3.9inch) inside diameter and an appropriate non-magnetic window.
Applications
- Development and quality control measurements of in-plane magnetic field effects in magnetic thin films, magnetic media and magnetic devices such as FeRAM and MRAM. The open geometry reduces the difficulties of access to the sample surface for radiation beams for MOKE (Magneto-Optic Kerr Effect) and SMOKE (Surface MOKE).
- Scanning Probe Microscopy utilizing Scanning Electron Microscopy with Polarization Analysis (SEMPA), Scanning Tunneling Microscopes (STM) or Atomic Force Microscopes (AFM) is more easily implemented by the open access to the sample surface.
- Calibration and test cycle times for Hall effect, MR (Magneto Resistive) and GMR (Giant MR) magnetic field sensors can be reduced by simplified robotics for device handling and faster control of field magnitude and direction.
- Chemical reaction rates and biological sample activity in magnetic fields may be more readily monitored because of the improved access for electrical and optical probes.
