Quantum Design MPMS/XL platform for magnetometry, based on a highly sensitive SQUID (superconducting quantum interference device) sensor that measures magnetic signals by extraction and/or vibration method (STO). Our instrument offers several options and measurement modes: magnetization up to 5T, DC and AC susceptibility (up to 1 kHz), all in variable temperature from 1.8 to 400K. We have options to perform angle-dependent measurements on single crystals, to illuminate the sample in situ, among others.

The NanoMOKE3 (Quantum Design – Durham Magneto Optics) is a hybrid of a MOKE magnetometer with Kerr effect microscope. It allows measurement of the magnetic properties of thin films and magnetic nanostructures for application in nanotechnology, magnetic RAM (MRAM), recording heads, structured magnetic support, spintronics and magnetoelectronics, GMR and TMR, thin film magnetics, and magnetic field sensors. Integrated and automated optics. Allows measurement of magnetization in longitudinal, transverse (with in-plane applied field) and polar (with out-of-plane applied field) configurations with high accuracy.
The institute has several magnetic, electrical and magneto-transport characterization equipment specialized in various aspects of materials science and nanoscience.

Measuring equipment consisting of a signal generator for rf magnetic fields at frequencies up to 20 GHz. This dynamic magnetic field is combined with a static magnetic field to excite the ferromagnetic resonance (FMR) of a magnetic sheet forming a bilayer next to a sheet of non-magnetic material. Using two lock-in amplifiers, it is possible to detect the FMR signal through a photodiode or the signal due to the inverse spin Hall effect in the non-magnetic material layer, produced by the injection of a pure spin current through the interfacial due to the excitation of the FMR..

The magnetotransport insert fits into the 1-inch bore of a variable temperature cryostat equipped with an 8 Tesla (vertical) and 2 Tesla (horizontal) 2D vector magnet. Different adapters allow the user to apply the larger magnetic field in the plane of the sample or perpendicular to it, while a closed-feedback rotary piezoelectric controller converts the 2D magnetic field into a true 3D vector magnet. Temperature range from 1.8 to 300 K. An octagonal chip holder provides up to 8 electrical connections terminated in BNC connectors on the outside. The insert is designed to allow simultaneous AFM measurements (MFM and PFM included).
