Measurement Systems


  • Physical Properties Measurement System (PPMS) EverCool II from Quantum Design.  This user-friendly system uses a coldhead to reach temperatures as low as 1.8 K without any liquid cryogens.  The system is capable of performing measurements of electrical resistivity, magnetic susceptibility, and heat capacity as functions of temperature and/or magnetic field.  It is equipped with a 9 T superconducting magnet.

PPMS Control Console and Dewar
  • 4 K Closed Cycle Refrigerator from Janis Research Company.  This system is able to reach temperatures as low as 4.2 K without any liquid cryogens.  We are currently setting it up to perform measurements of electrical resistivity and thermoelectric power as a function of temperature.  

Closed Cycle Refrigerator System
  • Kadel bucket Dewar system.  The bucket Dewar is being set up to perform measurements of electrical resistivity as a function of temperature using liquid nitrogen to reach temperatures as low as 77 K.  A custom dip probe is currently being designed and constructed to use in the system.

Sample Preparation Facilities

1500 C Box Furnace  

1200 C Box Furnace

Tube Furnaces
  • 1500 degree Celsius box furnace (RHF1500) from Carbolite Gero.  This is the work-horse furnace in our laboratory.  It is primarily used for synthesizing samples of different oxide compounds.  See the left-hand photograph above. 
  • 1200 degree Celsius heavy duty box furnace from Lindberg Blue.  The heavy duty furnace is able to reach a maximum temperature of 1200 C.  Its large inner volume accommodates large quartz tubes that contain oxygen- or moisture-sensitive chemicals.  See the middle photograph above.
  • Two MiniMite tube furnaces from Lindberg Blue.  These tube furnaces are used for sample synthesis and/or sample annealing.  They are able to reach a maximum temperature of 1100 degrees Celsius.  See the right-hand photograph above.
  • 1100 degree Celsius muffle furnace from ThermoFisher.  The muffle furnace is used primarily for drying chemicals and curing epoxies.


Analytial Balances

Nitrogen Dry Box

Diamond Wheel Saw
  • Sorvall ST 8 centrifuge from ThermoFisher.  The centrifuge is used to spin off the molten flux during single crystal synthesis.  The centrifuge is seen in the upper left-hand photograph above.
  • Two GH-202 analytical balances from AND Weighing.  These analytical balances are used to weigh constituent chemicals during sample synthesis as well as samples prior to measurements.  They are capable of measuring a maximum of 220 g and have a 0.01 mg resolution.  The balances are seen in the upper right-hand photograph above.
  • Nitrogen Dry Box from Plas Labs.  We have a nitrogen drybox to handle samples and chemicals which are air- or moisture-sensitive.  The drybox is seen in the lower left-hand photograph above.
  • Model 650 Diamond Wheel Saw from South Bay Technology.  We use our diamond wheel saw to cut samples.  The sample is secured to a goniometer with a high-resolution micrometer, which allows fine control over where cuts are positioned on a sample.  The goniometer also allows for 360 degree rotation of the sample.  The diamond wheel saw is seen in the lower right-hand photograph above.  
  • Fume hood.  Our lab is equipped with a fume hood for working with hazardous chemicals and/or chemical reactions (see below).

Miscellaneous Equipment

Stereographic Microscope

Hydraulic Press

Sputtering System
  • Two Leica stereographic microscopes.  We have two Leica stereographic microscopes that are primarily used for inspecting samples and setting up experiments (i.e., wiring samples).  One of the microscopes is shown in the upper left-hand photograph above.
  • Hydraulic press from Carver, Inc.  The hydraulic press has a maximum load of 25 tons.  It is used to compress powder into pellets during sample synthesis.  The hydraulic press is shown in the upper right-hand photograph above.
  • Hummer 6.2 sputtering system from Anatech USA.  The sputtering system is used to deposit a thin layer of gold on samples that have high contact resistances.  This procedure reduces the noise in electrical transport measurements.  The sputtering system is shown in the lower left-hand photograph above.
  • TitanTest leak detector from LACO Technologies.
  • T-Station 75 turbo pumping station from Edwards.
