Magneto Transport Characterization

Ferromagnetic Resonance (FMR) set-up

Ferromagnetic resonance (FMR) is a spectroscopic technique used to probe the magnetization of ferromagnetic materials. Our FRM system sweeps a range of frequencies from 2 to 17GHz and has sensitivity to detect signal in thin films down to 2nm. As an extra/feature, the system has  an optional waveguide to detect the Inverse Spin Hall Effect.

Giant Magneto Impedance (GMI) set-up

The GMI set-up measures magnetic field impedance dependence of thin films, ribbons and microwires from 30 kHz to 6 GHz for magnetic fields up to 120 Oe.

Alternating Gradient Magnetometer (AGM)

The AGM measures the net magnetic moment of a body upon the application of magnetic field. It works by sensing the force on the body due to a small ac gradient magnetic fiield. Our handmade AGM has a sensitivity of 10-6 emu and applied magnetic field up to 1 Tesla. The device takes magnetic hysteresis loops and first order reversal curves (FORC).

Magneto-Optical Ellipsometry

This is a versatile set-up that quantifies the change of polarization of monochromatic coherent light after a reflection on a film's surface. In this way it can work as a Ellipsometer and/or Magnetometer.

Induction Magnetometer

The induction magnetometer measure hysteresis cycles and first order reversal curves (FORC) of different materials, reaching a precision to measure micro threads and thin films.

Spintransport and Thermoelectric set-up

Our setup allows us to measure spintransport properties such as: Spin Seebeck effect, spin magneto resistance, etc. in addition to thermoelectric properties such as: Nernst effect, Anomalus Nernst effect, Ettingshausen effect, etc. We have successfully developed an alternative methodology to measure the Spin Seebeck effect with an unprecedented level of accuracy.

Microwave Assisted Magnetization Reversal (MAMR) set-up

Microwave-assisted magnetic recording has been proposed as one of the prospective recording technologies for forthcoming tera-bit-class magnetic recording. In this magnetization switching technology, the magnetization switches through excitation of its precessional motion by a radio frequency (rf) field.

Cryogenic Free Measurement System (CFMS)

System Cryogenic measures electrical and magnetic properties of materials from 1.6 K to 400 K and magnetic fields up to 9 Tesla.

Low-frequency vibrating sample magnetometer (VSM) and AC susceptibility with ultra-low field option.

Rotating sample platforms for DC Resistivity & Hall effect / AC Resistivity & Hall effect (1.6 K to 400 K).


UHV Sputtering System

Sputtering is a tecnique to deposit thin films onto a subtrate. Respect to other deposition methods, it works fine even with high meltin point materials, furthermore it allows 7 the co-deposition of alloys flims and complex multilayers with a notable degree of automation of the process.

Nano-Cluster Fabrication System

This equipment produces beams of clusters of metallic atoms and deposit them onto a substrate (15x15mm). The size of the clusters is highly tunable: can be as small as a single pair and as big as 105 atoms per cluster (mean diameter 0.5-15nm).

Morphological Characterization

AFM set-up

Our HpAFM from Nanomagentic Instruments offers excellent features such as alignment-free design, closed loop flexure scanner, decoupled z scanner, 10 MP video microscope. and flexible operating modes. The recent upgrades (liquid cell and environmental chamber) allows the system to work in liquid and in different environmental conditions.
