Many investigation lines in this institute rely on the magnetic and electric properties of the materials being investigated. Most of the characterization carried out requires the use of very precise measurement systems. In order to satisfy the intensive demand of measurements of this nature, the Low Temperature and Magnetometry Service was created.
The Low Temperature and Magnetometry Service is part of the ICMAB Scientific Technical Services Unit and its facilities are available to all the research crew of the Institute, as well as, to external users. It is devoted to the measurement of the magnetic, electric properties under specific conditions of external magnetic field and temperature.
In order to achieve the demand, the Service is equipped with two SQUID based magnetometers (Quantum Design MPMS system), devoted to magnetometry measurements and two Quantum Design PPMS systems, devoted to electrical transport measurements, as well as magnetometry measurements.
A User Commission supervises the proper operation of the Service and meets once a year in order to satisfy this supervision task as well as to take the appropriate decisions for the optimization of the Service operation.
The MPMS-3 system is the new generation of SQUID detector based magnetometers. It offers an enchanced performance of temperature stabilization, magnetic field stability when compared to those exhibited by the MPMS-XL system. This fact reduces the measurement noise, allowing the obtention of cleaner measurements for those samples with extremelly low magnetic moment. The core system consists of a superconducting longitudinal solenoid able to generate mangetic fields up to 70kOe. The system has also able to precisely control the temperature at the sample space at any value from 2K to 400K with a stability condition of less than 0.1% of oscillation.
Due to the nature of the equipment used, restrictions apply on the type of samples that can be submitted. The service will only accept samples that are prepared following the tips explained below.
Please, contact to the Service Manager for more details
The experimental setup allows only the use of bulk samples or thin fims not larger than 1x1mm2. The desired rotation must be clearly indicated either in the sample, or by using a drawing sketch.
Only bulk or thin film samples are accepted
