SQUID – Magnetometer

The Quantum Design MPMS 5XL SQUID Magnetometer with Evercool uses a superconducting quantum interference device (SQUID) detector to monitor very small changes in magnetic flux, and is extremely sensitive for all kinds of AC and DC magnetic measurements.

Quantum Design MPMS 5XL SQUID magnetometar sa Evercool koristi SQUID detektor (superprovodnički kvantni interferencioni uređaj) za praćenje veoma malih promena magnetnog fluksa i izuzetno je osetljiv za sve vrste AC i DC magnetnih merenja.

Magnetic moments down to 10-8 emu (10-11 Am2) can be measured in a reproducible way.

Magnetni momenti do 10-8 emu (10-11 Am2) mogu se meriti na ponovljiv način.

The MPMS has a temperature range between 1.9 K and 400 K, the superconducting magnet can reach magnetic fields between -5 T and 5 T.

MPMS ima temperaturni opseg između 1.9 K i 400 K, a superprovodnički magnet može dostići magnetna polja od -5 T do 5 T.

The advantge of the Evercool Dewar is that users are not required to cart liquid He in for measurements; the Evercool recondensor ensures that once the Dewar is filled with liq. He, any evaporative loss is recondensed, with the help of an attached gas line.

Prednost Evercool Dewar-a je što korisnici ne moraju donositi tečni helijum za merenja; Evercool rekondenzator obezbeđuje da, kada se Dewar napuni tečnim helijumom, svaki ispareni gubitak bude ponovo kondenzovan uz pomoć priključene gasne linije.

This makes the device very useful, and user friendly.

Ovo čini uređaj veoma korisnim i jednostavnim za upotrebu.

In our group, MPMS 5XL is manly used for measurements of static and dynamic magnetic properties of nanosized magnetic materials, such as 3d and rare earth metal oxides.

U našoj grupi, MPMS 5XL se uglavnom koristi za merenje statičkih i dinamičkih magnetnih svojstava nano-magnetnih materijala, kao što su oksidi 3d i retkih zemnih metala.

This will provide the possibility to correlate nanomagnetism with the intrinsic structural properties of nanosized systems.

Ovo omogućava povezivanje nanomagnetizma sa suštinskim strukturnim svojstvima nanosistema.

The overall amount of collected data will enable the probing of the existing models and contribute to the deeper understanding of the nanomagnetism.

Ukupna količina prikupljenih podataka omogućiće proveru postojećih modela i doprineti dubljem razumevanju nanomagnetizma.

They will also serve as the basis for the design of magnetic materials suitable for biomedical and technological applications.

Takođe će služiti kao osnova za dizajniranje magnetnih materijala pogodnih za biomedicinske i tehnološke primene.

Applications of the SQUID magnetometer include the measurements for the characterization of all kinds of magnetic materials in physics, material science, chemistry, geology, electronics and biology.

Primene SQUID magnetometra uključuju merenja za karakterizaciju svih vrsta magnetnih materijala u fizici, nauci o materijalima, hemiji, geologiji, elektronici i biologiji.

Multiple options of this device create a powrfool tool for studies of very wide range of materials, their properties and phenomena as antiferomagnetism, artificially layered structures, biophysics, fullerens, Hall Effect, heavy fermions, high and low temperature superconductivity, hysteresis, paramagnetic films, spin glass materials etc.

Višestruke opcije ovog uređaja čine ga moćnim alatom za proučavanje veoma širokog spektra materijala, njihovih svojstava i fenomena kao što su antiferomagnetizam, veštački slojevite strukture, biofizika, fulereni, Holov efekat, teški fermioni, superprovodljivost na visokim i niskim temperaturama, histereza, paramagnetni filmovi, spin-stakleni materijali itd.

Beside that, MPMS plays an important role in the effort to understand and optimize the synthesis process of materials such as amorphous alloys, inter-metallic compounds, magneto-optic materials, mesostructures, multi-layerd materials, rare earth compounds, superconductors, thin films, transition metal oxides and weakly magnetic materials.
