Abstract/Description: We studied the relationship between superconductivity and magnetism in the heavy fermion CeCoIn5 using a miniature cell in a top loading dilution refrigerator with a 16 T magnet (XCF – Xtreme Conditions Fridge). The construction and measurement techniques for a miniature cell are discussed. We were able to observe a first order superconducting phase transition with an upper critical field Hc2 at roughly 0.2 K. It changed position and shape with angle and magnetic field sweep rate because of CeCoIn5's anisotropic crystal structure and small heat exchanges through the wires used in the calorimeter.
