MagRS Magnetic Research System

The MagRS FMR measurement option enables you to easily use a NanOsc Instruments PhaseFMR or PhaseFMR-40 spectrometer with the 4 in or 7 in MagRS magnet systems for ferromagnetic resonance (FMR) measurements. It provides hardware and software integration of NanOsc instruments and u-type CPW sample holder products in a room temperature application.* With it installed, broadband 2 to 18 GHz (PhaseFMR) or 2 to 40 GHz (PhaseFMR-40) measurements in variable DC magnetic fields are possible. Maximum fields depend on the system and whether in-plane (IP) or out-of-plane (OOP) orientation is used . Measured and fitted data for Ni80 Fe20 (10 nm)/Ta (5 nm) thin film as a function of IP field to 0.94 T at frequencies of 30, 32, 34, and 36 GHz (typical results)

* Does not include NanOsc CPW, Helmholtz coils, cables, and FMR instruments. These NanOsc room temperature FMR products are available from Quantum Design, our preferred source of NanOsc products

The MagRS VSM option brings cutting-edge levels of measurement performance to magnetic characterisation. The system features ultra-high sensitivity (down to 15 nemu), wide dynamic range, faster field ramping (10,000 Oe/s) and rapid data acquisition (up to 10 ms/pt). A complete -2 T to +2 T hysteresis loop with 3,000 measurement points can be completed in about 30 s. Field setting resolution of 1 mOe is available across the entire measurement range, and especially helpful in regions where moment gradient ΔM is high. This fine resolution, combined with high sensitivity and fast measurement speed, makes the MagRS VSM ideal for first order reversal curve (FORC) measurements, which inherently involve very large data sets.

Using the M81-SSM, the ETransport option allows ultralow noise AC and DC transport measurements. The system uses a central instrument with remote source and measure modules for the shortest possible signal path to the DUT, separating sensitive analog circuits from digital circuits and unwanted sources of interference typical of traditional instrument designs.
