Specifications of MPMS XL-5Field =5 TeslaTemperature=1.7K to 400 KSweeping rate=0.001K to 10K/Min
Possible Measurements Magnetization vs. Temperature (M vs. T):Default settings: 300K-10K, Temperature interval 5KZero Field Cooling Field Cooling AC Susceptibility Magnetization vs. Field (M vs. H):Default settings: -5T to +5T step size 0.5T Hysteresis Hysteresis
Features of MPMS MultiVu Software Simultaneous Access to all aspects of system operation: sequence setup,data analysis,data display Enables multiple documents and view to be visible and useable at the same time Simultaneous display of data files in multiple formats (e.g.. Graphs vs. texts) Automated Background Subtraction
Limitations Measurement of hysteresis at more than two temperatures is considered as II sample Measurement below 10K also considered as II sample (because it is necessary for the instrument to be stable at 10K at least for 1 hour before going below 10K) Sample should be submitted only on Friday
