Scientific & Technical Services

Low Temperatures and Magnetometry Lab

The Low Temperatures and Magnetometry Lab allows for very precise magnetic and magnetotransportation measurements, useful for most characterization efforts that usually require knowledge on the magnetic and electronic properties of the materials investigated.

Scientific equipment available

Quantum Design MPMS-XL (SQUID): Magnetometer based on a SQUID detector that allows for the detection of extremely low magnetization signals as well as its dependence as a function of the applied magnetic field and temperature.

Quantum Design PPMS System: A multipurpose platform that allows for a complete characterization of the magnetic and electronic transport properties of materials under extreme magnetic fields (up to 90 kOe) in a broad span of temperatures from about 400 K down to 1.8 K.

New equipment, contracts, techniques
  • A second Advanced Liquefier Technology (Quantum Design-ATL) unit was acquired, to increase the recycled helium to 90-95 % of the total consumption.
  • A new tender for the acquisition of a new magnetometer was opened in 2019, which will be installed during 2020. Finishing the tender process for the acquisition of a 16T cryostat.

Use of the Service in 2019

The service has been used for a total of 6558 hours, divided between internal users (6000 h) and external users (558 h). This corresponds to 1235 measurements sessions, and 604 requested services, from 22 IPs and 52 ICMAB users.

The external users are the following: ICN2, ICFO, UAB  - Chemistry Department, UAB – Physics Department, Universidad de Granada, Universidad de La Laguna, Universitat Politècnica de Catalunya and users from the project NFFA

A total of 10,434 L of helium were consumed, of which 7,314 L (70 %) were recycled and 3120 L (30 %) were purchased.

Outreach, publications and projects in which the service has participated

The Low Temperatures and Magnetometry Lab has participated in many outreach activities, including many school visits for primary and secondary schools, and has participated in the Argó Program during summer 2019.

The service is co-author of the following publication: Non-stoichiometry Driven Ferromagnetism in Double Perovskite La2Ni1-xMn1+xO6 Insulating Thin Films. Monica Bernal-Salamanca, Zorica Konstantinović, Lluis Balcells, Elisa Pannunzio-Miner, Felip Sandiumenge, Laura Lopez-Mir, Bernat Bozzo, Javier Herrero-Martín, Alberto Pomar, Carlos Frontera, Benjamín Martínez. Crystal Growth & Design 2019, 9, 5, 2765.

The service has participated in the following projects:

  • Generación y detección de corrientes puras de espin en heteroestructuras de óxidos, RTI2018-099960-B-I00
  • Designing Advanced Functionalities through controlled NanoElement integration in OXide thin films – DAFNEOX - H2020-MSCA-RISE-645658
