Shared Facilities 

PPMS This equipment multiplies the capacity of the labs. of the network to characterize samples in a wide temperature (1.8 K- 400 K) and magnetic field range (up to 9 T).  The PPMS integrated measurements applications include heat capacity measurements (automated relaxation technique), electrical transport characterization (DC Resistivity AC Transport), thermal transport measurements (thermal conductivity and Seebeck coefficient) and magnetometry (AC susceptibility with 10-8 emu resolution and DC Magnetization  with 2.5×10-5 emu resolution). This equipment is presently installed at the Facultad de Ingeniería (UBA).

SQUID magnetometer (MPMS) : It is an essential device for the network in order to perform high precision DC magnetization measurements in small samples as thin films and small single crystals that can not be measured by the magnetometer of the PPMS system. Moreover, it’s an indispensable equipment to characterize nanometric compounds with low magnetic signal. The best available VMS magnetometers allow measurements in magnetic fields up to 2 T with a precision of 10-7 emu at room temperature. At lower temperatures, all these possibilities are notably reduced. The MPMS SQUID should allow measurements with a 10-8 emu sensitivity at higher fields in all the temperature range above 2 K. That would produce a qualitative leap both in the spectrum of samples able to be characterized and in the quality of experimental results. The SQUID is presently installed at the LBT of the Faculty of Sciences (UBA). More info ar http://www.lbt.df.uba.ar/SQUID/SQUID.htm

ESR spectrometer The BRUKER 300 ESR spectrometer, installed at the Magnetic Resonance Laboratory of the Centro Atómico  Bariloche, is an essential tool for the project.  It has been in continuous operation since 1986 at X-band and the facilities were extended to Q- and L- bands in 1991.
